The WonkaMeister is well versed in probability, bell curve, regression to the mean, theory of runs, gambler's fallacy, martingale system, etc. For instance, he knows that 27 in a row, is the equivalent of winning the MegaMillions lottery. (true fact) Also, in 1913, at a casino in Monte Carlo, black came up a record 28X in succession. He knows that there is a wealth of online information pertaining to streaks of 10, 11, 12, etc., most of it addressed as "well the next coin flip has no memory of the last, they are independent trials". He can't find anything on the extreme odds that his expieriment is revealing. The WonkaMeister is ca$hing in on this streak area between 22-30. He doesn't want to fade the commoners at zero, he wants to begin fading the select few Umpa Lumpas that make it close to the end zone. He believes that if he started betting against the commoners, he'd bust out his bankroll with an unfortunate run. In theory, can the WonkaMeister capitalize on this strategy? Betting that individuals on the insane tip of a bell curve, will experience regression to the mean?

BTW, cutbacks within the operation, forced the WonkaMeister to release 500 Umpa Lumpas to Willy Wonka. Hence the backstory behind the iconic characters you see in the movie.
