Hi Gary,
I was surprised. I was under the belief that the more games a junior played in a season, the harder it was towards the end of the season to affect that grade. I was pleasantly surprised when I ran the simulation to find that this was not the case.
I didn't quite understand what you meant by rolling grades, now I do from your last post. This is the system they use in the ECF at the moment!
Mathematically the use of N = 30 keeps the grade change between+- 24.5 grading points for games 1-30
If we change to 20 it becomes +- 36 and 15 becomes +- 48! (using change = 800*(actual-expected)/n )
