Bump.
Today I started sparring with 7063 points. I sparred 3 wins, and had 7183. I then sparred 3 losses and ended up with 6949. I began counting my wins and losses. 30 wins and 5 losses (in no particular order)? I end up with 6488. I'm pretty sure winning six times as much as losing is not worthy of dropping 500 points.
No, I don't spar new players with low scores. I spar anyone and everyone in the room. Something should be done, in my opinion.
