Other than giving a guess at where a fighter is at each level? How does primary's affect actual matches. Does having a higher boxing primary give you an edge over your opponent and say you have high bjj primary but low submission? does the primary still make the fighter good on the ground?
Can you spar different types of sessions back to back such as boxing sparring in the am slot and bjj in the pm slot on the same day? or would that also be bad?
