Ok, I found a site that calculates scores based on percentage and shows the final grade:

Try putting in ANY of the scores that I posted, and the grade will come out the same way as it is on my screenie. To calculate the marv's, just combine them with the perf's and put that as how many perf's it is on the calculator, then add the others. Each grade comes out to exactly what it should be. So there. XP
