I'm not sure if that is the right calculation.

Provided the flops are not prohibitive. Output quality per model bytes might be better. In general people run the largest model they can.

I certainly think trading speed for quality at the same size is worth looking at. Especially if it uses methods that can benefit from the efforts of others to improve speed in general.

That said performance difference at 30M may not be representative of performance difference at 30B

There are probably a lot of really good ideas out there waiting for someone to drop a few million in training to reveal how good they are on large sizes.
