Each flop is solved with postflop-solver, an open-source CFR+ solver, until the strategy is within 0.3% of the pot of unexploitable. The tree has two bet sizes on the flop and is a fixed abstraction, so a finer tree gives different numbers.

Suits only matter for flushes, so flops that differ only by relabelling suits play the same. That leaves 1,755 classes out of 22,100 flops, each weighted by how many real flops it stands for; the averages on this page use those weights.
