Do you do more than12 sets?

[Upper-cruster]

I usually do 12 sets/10reps per large muscle and 6-8 sets/10 reps for small muscle.

Is there a better/optimal range of sets/reps? Why?

The rule is that fewer reps/heavier weights about and a rep count below 6 reps builds up strength

6-14(or something) maximizes volume

above 14 or so is for endurance.
