Why not? You have far more results to review.

If you run a model on slower hardware are you getting more experience? Surely its a factor of model output reviewed and not human time.

Right, it's about how much time the human spent - the time spent by the machine itself is irrelevant. As you rightly point out: that is why we measure programmer experience by wall clock time, not CPU time :)
