I have been doing full squats for quite some time, and there is a question which keeps on bothering me. For example there are 2 people who have roughly the same strength in squatting, say 315lb max full squat. Now one of them keeps on doing full squats, and one of them switches to quarter squats. Undoubtedly the person who does quarter squats will be using heavier weights from now on.

So after 3 months, who will be stronger in doing quarter squats?

Of course the person who only does full squats will still be better in doing them, but could he/she still outlift in doing quarter squats?

Thanks for your time.
