1. The Statistical Method: American Football Betting and Italian Soccer Pools (1, X, 2)

We know from my probability book that the past does count in all random events (in everything, that is). For one, the past is represented by the number of trials — one of the three essential elements of the Fundamental Formula of Gambling FFG. This is how I started my gambling theory. Statistical analyses can discover tendencies. A tendency is, simply put, a repetition of something across a number of trials.

Back in Romania, I loved to play soccer pools: 1, X, 2. 1 represents a win for the home team; X is a tie (very rare in the American football; very common in the Italian calcio leagues); 2 means a win for the visiting team. I needed to devise a strategy to give me the best results based on statistics. The system was best suited for the Italian soccer championships (Serie A and Serie B). The Italian soccer games have a high level of unpredictability. In most other national championships, the results are more easily predictable (the home teams win in most cases).

I did not write standalone software for this type of gambling mathematics. Instead, I created two Excel 95 spreadsheets. They are still available from my website, although data is outdated now. The user can update all figures, however. Long live the Internet!

The European football (soccer) Excel spreadsheet is named Toto1x2.xls. It is based on real data from the 2001 Italian football championship Serie A.

The American professional football Excel spreadsheet is named NFL2001.xls. It is based on real data from the 2001 NFL regular season.

I will present now an abbreviated form of my system applied to the American football (specifically the NFL). As I do not offer a computer program at this time, you can apply this strategy manually (pencil and paper) or edit the spreadsheet.

You will keep records for each team, separated in two files (spreadsheets): Record at home and record on the road. Using the overall records has much lower relevance in the American professional football. The betting is based on a parameter named point spread. A team is expected to win alright. But it must win by a specific margin of victory (the point spread or simply the spread).

You will work with these two very important elements: Home Team At_Home and Visiting Team On_The_Road.

In this abbreviated version, you will use only the results (win/loss) and the points scored/allowed. Add the wins for the home team at-home with the losses for the visiting team on-the-road. Do the percentage. Normally, a percentage over 75% is a good indicator for a home team win. The average scores can offer additional useful info. In the case bellow, the game was very close to call: Just a slight advantage for the Home-Team. But the Visiting-Team had a realistically good chance to win (based on points scored and points allowed.

Using my strategy for the Italian soccer leagues, I predicted 9 even 10 (out of 13) games (70% or 77%). That is, I predicted with only one prognostication sign: 1, or X, or 2. Then I would use two signs for close games (1X, or 12, or X2), even 1X2. The soccer prediction is based on the win/loss parameters. The scores are disregarded. Thus, the soccer betting appears to be simplified, compared to American football betting.

I lived as a refugee in Yugoslavia for eight months, between 1984 -1985. That's when I had the most success playing soccer pools. I helped also the Yugoslav office of the United Nations High Commissioner for Refugees (UNHCR). I translated statements and documents from Romanian into English. I enjoyed doing the job. I helped others and I helped myself by practicing English and getting to know more about the Homo Computing_beast experience. It is the name I find to be most truthful for this extraordinary species.

UNHCR promised to pay me. I would hear “Sutra!… Tomorrow (in Serbian)… Next week…” The main problem I had then: My shoes were real bad. Granted, they helped me to cross the border. But I had reached a point I needed a pair of better shoes. I turned to an old friend: Gambling. Specifically, the soccer pools. I won a couple of times playing the Yugoslav soccer championship. As in most countries, there were not many surprises to lead to big prizes. Then, a medieval, beautiful winter set in. Every country in Europe would use only the Italian soccer games for their pools. I hit the second prize. Actually, I predicted all the games, but I applied a minus-1 system (a wheel). Anyway, the prize paid good money, especially by the standards of a shoe-challenged refugee.

I didn't have time to do anything, after cashing in the prize. Just about everybody in my “politically-correct” entourage wanted a big party. The refugees live under tremendous stress, in case you didn't know that. So, I said, yeah, let's do it, we need it! I thought everybody got drunk that night, but not everybody did. Because somebody stole all my money over night! Nothing was left in my pockets after the big party! Truth is, I arrived in America wearing bad shoes, perhaps to prove to myself the American dream. "Give me your poor, your shoeless, etc."

• • Let's change gears and take a look at a real-life game in the NFL and the stats for the two teams.

Home Team: At-Home
Week 	Wins 	Losses 	Points Scored 	Points Allowed 	
Week 1 	1 	0 	20 	13 	
Week 2 	1 	0 	13 	10 	
Week 3 	0 	1 	20 	27 	
Week 4 	1 	0 	21 	14 	
Total 	3 	1 	74 	64 	
Average 	75% 	25% 	18.5 	16 	

Visiting Team: On-the-Road 
Week 	Wins 	Losses 	Points Scored 	Points Allowed 	
Week 1 	0 	1 	20 	31 	
Week 2 	1 	0 	21 	14 	
Week 3 	0 	1 	16 	35 	
Week 4 	1 	0 	24 	13 	
Total 	2 	2 	81 	93 	
Average 	50% 	50% 	20 	23 	
Predicted Result Based on Wins/Losses:

Win for Home Team: 3 (wins at home) + 2 (Visitor losses) = 5 of 8 (62%)

Win for Visiting Team: 1 (Home losses) + 2 (Road wins) = 3 of 8 (38%)

Home Team
Average points scored: 18
Average points allowed: 16

Visiting Team Average points scored: 20
Average points allowed: 23

Predicted Score: 20 - 18 in favor of Home-Team.

The prediction for this NFL game was derived from 4 games only. The success ratio increases with the increase in the number of games. The results get better in the second half of the regular season (after Week 8). Using data from previous seasons is very often misleading. The teams in the American sports change constantly as a result of the free agency. Players move from one team to another. Some players have a real impact on the game.

The success (correctness, performance) rate of SPORTS.XLS, the Excel spreadsheet for sports betting, is around 2 out of 3. Actually, it is higher at picking straight-up winners or pick-'em. It can still hit at least 60% when applied to point-spread betting, as in the American football.

A 60% success rate translates equivalently that a player can pick one game at a time and be successful in 60% of the cases.

If picking 2 games, the probability goes down to: .6 x .6 = .36 or 36%.

Picking three games: .6 ^ 3 = 21.6%.

A 5-team parlay can expect a success rate of .6 ^ 5 = 7.7%.

The most favorable case is for straight-up betting: One game only. The house advantage (edge) is also the most favorable: 10%. That is, a 1-unit bet returns a .9-unit payout. Usually, American football bettors pay 110 dollars for a 100 dollar win.

A five-team parlay offers, at best, a 25% house advantage. Ten or more game-parlays go to over 90% in house edge! It is outrageous!

If betting straight-up 10 times (or weeks, as in NFL pro football), the player should expect 6 wins and 4 losses. The four losses result in 4 units. The 6 wins amount to +(6 x .9) = +5.4 units. The net win is 1.4 units. If betting $100 at a time, the net profit should be $140 over a period of 10 weeks. Just for fun, unless thousands are bet per game.

A probability of over 50% yields also longer winning streaks and shorter losing streaks. The mathematical player can draw a big advantage from that probability feature. The non-mathematical bettor should keep in mind that an over-50% probability tends to repeat in the very next trial; a bet increase is favorable. Conversely, a 60% probability event will not lose very often more than three consecutive trials; again, a bet increase after three consecutive losses is good money management.

My spreadsheet strategy applied to American football prognostication was pirated even at a Microsoft site! One visitor to my sports forum advised me of the incident.

Here is an excerpt from the Microsoft site (the URL is

That page was published several years after I released my sports betting theory and spreadsheets (year of grace 2000).

Randomness in sports betting resembles the lottery play, is the idea of the best-ever sports bettor.

2. The Randomness Approach: Resemblance to Lottery Games

How about random play, like quick-picks in lottery? It could help the biased sports betting player. Many sport bettors have a bias towards favorite teams, including football. Reality is that only a tiny minority of teams are dominant. Therefore, most biased players are losers. They would be better off choosing the winners randomly. I offer free software to pick sports results in a random manner, like the lottery. This section lists the most important free programs that generate random sports picks—as numbers and also team names.

A program I wrote in August 2003 has become a big success: PermuteCombine. The combinatorial software generates permutations, arrangements (some say permutations of N, M; like exactas and trifectas at horse racing), combinations (like in lotto), and exponents (like in the pick-3 lottery and soccer pools 1, X, 2).

The program generates numbers or words (such as names of sports teams). There is a sample text file — TEAMS.NFL — with all 32 NFL football teams. The option applicable to the American football is Arrangements; Words; Random. The option applicable to soccer pools (1, X, 2) is Exponents, Words, Random (use the sample file 1X2.TXT).

It's best to run a random option several times in a row. Common sense tells you that hitting in a first try is a very rare event in gambling. The high-eyebrows translation (probability theory) is: The degree of certainty DC rises with the increase in the number of trials N, while the probability p is always constant. Repeating the combination generating process affords to you compression of time and costs.

Here is an interesting fact I discovered. Please relate it to the role of standard deviation in random events (the watchdog of randomness, chapter IV). I applied this NFL strategy live at my website. That is, I published the predictions days before the games were played. I recorded the results after the games ended. The new page was published with the new data. I had misses and I had wins. The project covered almost three regular seasons in the National Football League (NFL). The results were quite impressive: 27 wins out of 41 weeks. Success ratio: 65.9% (2 out of 3 times). See the page at SALIU.COM: random-picks.html.

I applied the strategy to five games. There are two outcomes in rapport to the betting line. Either choose the favorite to cover the spread (win by the point spread); or bet against it (take the underdog to defend the spread). Total amount of possible combinations is therefore 2^5 = 32.

The Fundamental Formula of Gambling demonstrates that, in a majority of cases, the winning combinations will come from the FFG median zone. The FFG median zone and the normal (Gauss) bell share a large percentage of elements, but the areas are not identical. Percentage of 25 combinations within the FFG median bell: 38% (or 12 lines of 5 teams each, from index #11 to index #22).

My site also publishes the schedule of NFL National Football League (I have pages starting with the 2004 season results). When this project was running, I copied the schedule from the official site of the NFL. Let's say that a particular week had 16 games scheduled. I ran PermuteCombine, the Combinations, Numbers, Random option for 16 numbers, 5 numbers per combination. Total combinations to generate: 22 (the median calculated by the Fundamental Formula of Gambling for a probability equal to 1/32). The combination #22 for that particular run was: 4, 5, 7, 8, 11. In the case described at my site, you can see what games those 5 numbers represented in that week's schedule. The schedule starts with games #1 (of course!) and ends with game #16. For example, game #4 that week was Texans at Jaguars.

The winning combination for that particular week was:
Jaguars, Colts, Chargers, Vikings, 49ers,
or lexicographical index 20 (a winner — inside the FFG median area 11-22).

The accounting or the auditing now:
Total games to play every week: 12;
Total weeks played: 41
Total games played: 41 * 12 = 492;
Total winning weeks: 27;
Payout for a winning 5-team parlay: 25;
Total winnings: 27 * 25 = 675;
Net profit: 675 – 492 = 183.

Not long after my project, most bookies lowered the 5-team parlay payout to 20-to-1. The total winning would go down to 27 * 20 = 540. Still, a profit (48 betting units). Since the winning percentage is well above 50%, increasing the bet after a loss offers a great benefit overall. I would even start martingaling after 3 losses in a row! There was one occurrence of three consecutive losses during the 2002 season. The Martingale betting could have started after just two consecutive losses and the profit margin would have been phenomenal!
