Technician will activate on Variably damaging moves under 60 Base Power. Moves like Payback, Pursuit, and Revenge, when the extra power is added on, will get a Technician boost. Look at Payback like this:
PAYBACK:
50 1.5 2 = 150 BP. (Minus STAB)
Or
REVENGE / AVALANCHE:
60 1.5 2 = 180 BP. (Minus STAB)
Remember: Technician boosts ALWAYS get added first.
