(3 × $0.050 + $0.100) ÷ 4 = $0.063/1M — the $/1M figure blends input and output at 3:1 — that is the only way models with two different rates can be ranked on one axis. Your actual rate depends on your own input:output mix — input only $0.050, 3:1 $0.063, 1:1 $0.075, output only $0.100 per 1M.

The board shows this model's cheapest measured offer ($0.063/1M); the smaller figure under it is the mean of the 44 offers listed below ($0.290/1M). Add those up and divide — it matches.
