T-Rod, the point isn't the billion hands. The point is that you have zero reason to expect that it will "even out," in the sense that you will flop more sets than expected, over ANY time period in the future.
Let's say you flopped 0 sets over 1,000 hands with pocket pairs. A serious statistical anomaly. Then over the next 9,000 hands, you flopped the normal number over every 1,000 hands: exactly 117.
Here's your data set in format (X, Y) where X = pairs, Y = sets
(1000, 0) ==> 0.00% sets
(2000, 117) ==> 5.85% sets
(3000, 234) ==> 7.80% sets
(4000, 351) ==> 8.78% sets
(5000, 468) ==> 9.36% sets
(6000, 585) ==> 9.75% sets
(7000, 702) ==> 10.03% sets
(8000, 819) ==> 10.24% sets
(9000, 936) ==> 10.40% sets
(10000, 1053) ==> 10.53% sets
This data set is "regressing to the mean." By percentage, you are getting closer and closer to 11.7 percent of sets flopped. But by number of sets flopped, you are remaining exactly 117 sets lower than would have been expected. There is no time period over which you (can expect to) flop more sets than expected.
In short, "regression to the mean" simply does not mean that you ever get to flop more sets than expected, over any time period.
