Does anyone know the cap for Crit Rate?

Consoles are the way to go. It looks like your drive's main stat is crit rate, but the best main stats are elemental damage bonus and crit damage.

The absolute best is having all four stats: Attack, Crit Rate, Crit Damage, and Defense. For the cycle stats, just increase the cycle strength. The cycle maxes out at around 360.

With an additional 12 from doping and 4 from affinity buffs, it reaches 89. You're short 2 from Drive, so you can secure 91% crit rate with Janhong's base stats alone.
