I pushed this change, then found out it was a bit broken (failed to recognize old optional .r option, and it seems initialization of the size_ratio field with memset produces a float value > 0.0). Just pushed a fix for that. And now I found that speed's handling of toom22, toom32 and friends always use fixed ratios, so I have to extend that to be able to get any interesting benchmarks when varying the ratio.
