Realised pretty quickly this is a function of rate, so I went straight for rate 1.

Playing with the data later is desmos, found the "quadratic regression" button, which matched the data perfectly to: metric = 100 * (rate - 16/7)^2

This is a rate 2, period 4 solve that runs 7 times, then waits 4 cycles. It makes 14 product sets every 32 cycles.
