Well I guess it's different for everybody. I know for me, that if I aim for exhaustion at 12 reps (so I adjust the weight accordingly), I'll put on the most muscle. If I aim for 6 reps (lifting more weight), I'll be able to lift more in one go (like those olympic weight lifter guys). And if I do 20 - 30 reps (less weight), it'll be like slim toned muscles, that can keep going for hours doing whatever they do. It's more aerobic.
So for girls it might be different though, because you guys put on muscle different than we do (you'd get slim I think whereas we'd get bulkier).
But I'd definitely think about puting more rest into your schedule, like the saying goes "it's better to miss a workout than miss a meal" - the same goes for the recovery period, that's the time the muscle fibres are actually being built.
And if you are aiming for 15 but can pull off 20, then add weight... I think the goal for you as well would be to reach exhaustion (but check with that trainer)
