(3 × $0.015 + $0.070) ÷ 4 = $0.028/1M — 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 $0.015, 3:1 $0.028, 1:1 $0.042, output only $0.070 per 1M.

The board shows this model's cheapest measured offer ($0.028/1M); the smaller figure under it is the mean of the 33 offers listed below ($0.089/1M). Add those up and divide — it matches.
