What would be a good starting point for gearing if I'm running a 21.5 lipo setup for my CRC Gen-X 10?

Looking at the Novak site and comparing 1/12 to 1/10 and 17.5 to 21.5. I'd guess I should be very very confused. For VTA we have the 4.2 ceiling and there is really nothing else to compare it with. The motor should be able to handle mid 3s to mid 4s, but somehow come up with numbers in the low 2s trying to get a 83 mm rollout.

I'm so lost.
I'll have to double check this (spur size), but I believe I'm running a 75T spur and I know pinion is 32T (48P). Tires are 2.180 dia. and rollout is close to 3.0 or 74mm.

Running speed pasion 21.5, on med sized carpet track. I'm close to speed of 13.5 4 cell with a little lacking low end power. temps 140-150 range after 5-6 min.
