just curious because on one of mine the subs were
Centering 10
Edges 9
Corners 8
Surface 9.5
If I add those up and divide by 4 I get 9.125 but the overall grade was 8.5 instead of 9.
Am I missing something or is there more to calculating the overall grade ?
what y2hood said. but generally, you wont get a grade more than a half point higher than the lowest grade (there are exceptions: weve seen a fuill point higher and even a point and a half, but those are extreme, like when three subgrades are 10's and one subgrade is a 5)
certain sets are weighed differently than others when it comes to subgrades as well
but it most definitely isnt an average
