Poisson Calculator
Probability / Odds of expected number of goals using Poisson distribution
If you have some expectation of number of goals in a match, one of the best ways to turn them into odds is Poisson distribution; it will give you probability of certain number of goals to be scored, and dividing 100 with probability gives you odds.
This spreadsheet has two sheets, “Total Goals” and “Correct Score”.

Leaning Towards Average
Strategy to evaluate expected match outcome and expected number of goals on the basis of recent team performance in comparison to “average” team performance, assuming that as the season goes by, average number of goals scored and conceded by each team is more accurately defined, thus allowing comparison of team performance against average performance; therefore I named this strategy Leaning Towards Average.
This strategy has been inspired by article at Understanding Uncertainty blog, and later on discussed in Punter’s Lounge thread What do I need to know to use Poisson?.
Spreadsheet contains example for beginning of the season in Championship 2010/2011.

Calculator of Double Chance and DNB Odds
This calculator allows calculation of Double Chance and DNB (Draw No Bet, Asian Handicap (0)) Odds based on 1X2 Odds.
Excel 2003 file, 25 kB
A reply to wasai’s comment, 28. December 2011: Overround of DNB odds is not given in advance, it cannot be set before calculation. DNB odds are calculated on the basis of 1×2 odds/probabilities.
So, in this example, overround is 114.22%, and odds were taken from real bookmaker’s offer. If bookmaker offered higher odds, for example, 2.40 on Home Win, 3.20 on Draw and 3.05 on Away Win, overround of DNB would be 108.30%.

The Perfect Martingale System
Spreadsheet created upon Punter’s Lounge thread The Perfect Martingale System:
The rules are simple. I will lay Under 1.5 Goals for a £10 stake. After one goal I will then lay Under 2.5 Goals for my £10 stake + the liability for the first bet. If another goal is scored I will lay Under 3.5 Goals for my £10 stake + all the previous liability. I will keep going until the the 87th minute. To protect me against a goal in injury time I will then lay the current correct score to cover all my liability on the Under markets.

Premier League Predictions at Betfair Banter forum
Each week I am trying to beat the Betfair Premier League Football odds by comparing my estimations of the probability of each outcome with the Betfair odds and betting on the one that differs the most.
The spread sheet does the maths for you, even if you want to use Kelly staking rather than level stakes, all you have to do is input your % estimations and the Betfair odds and the sheet will tell you who to bet on.
It’s pretty good fun so why not have a go yourself!

Keeping records, by Betfair Banter forum
We all know how important it is to keep record of your betting and I’ve decided to up my game in this area of my betting too.
I’ve created a spreadsheet that allows me to keep track of all my bets in different sports and tell me how well I’m doing in each. It also tells me how well my bets fair with level stakes so I can see whether I’m winning or losing due to poor staking or upping my stakes too early.
