Who is ahead on which flops
Paired flops are the best for A8s (73.52%); low rainbow flops (nine high or lower) are the worst (51.27%). A8s stays ahead on all five textures, but the swing between them is large, so how the flop looks matters a great deal.

|---|---|---|---|---|---|
| Rainbow, ten or higher | 25.254 | 72.352 | 2.113 | 25.535 | 73.409 |
