Yes and no. Someone who's marched multiple years with a winning corps has a leg up, but did they win solely because of their effort, or were they given a vehicle that enabled the win? And was their effort the same as the effort of the other 149 people? I've met people in every corps that work harder than their final placement would show, and some at the top who get carried along all season to the win, without the same effort. Which person is more qualified?
