Finally, a small program to help slot auditors and regulatory staff determine the actual expected hold % of a slot machine based on handle pulls and PAR sheet. The program uses standard deviation and Z-score, combined with volatility from the machine's PAR sheet and total handle pulls (MTD, YTD, LTD, it's up to you) from the machine's statistics to determine what the anticipated hold % should be. Compare that to the actual hold (Coin in / Net Win) to calculate the variance and determine if investigation or repair is necessary. Don't guess anymore, take advantage of this small utility.
If volatility isn't on your machine's PAR sheet, use the PAR sheet calculator utility to determine what the standard deviation is for that game based on reel stops, payouts per stop. All from the PAR sheet that came with the game.
