Where these numbers come from
Heads-up equity comes from the same preflop table the odds calculator uses, which averages each pair of hands over every board and suit pattern. Against a random hand, your own two cards make some hands less likely: holding an ace leaves three aces for the other player, so each hand counts once for every way it can still be dealt. Equity against several players is sampled with a fixed seed, so it can move by a few tenths of a point from the exact figure. The flop figures count every one of the 19,600 flops.
