Between Lvl82&83 I had a 66avg. When I made master (really don't know how I got there), all hell broke loose. Immediately after Master, my average went to 70.5, without playing. If your not dead on, you'll miss. Not much lee-way. My avg. now is 75ish....going up. There seems to be a noticeable speed up of the meter halfway through its progression. I'm hell-bent of taming it but I'm not having much success.
