Well, my spar is garbage plus I dislike spar, so gimme that 8-1. Would rather have a great ratio that I don't have to ever touch again then one that shows I've put massive amounts of Time into an activity that I don't enjoy(I could enjoy it again someday, but that's true for me right now).
If I could reset my ratio to 0-0, I would probably spar till I was something like 1000-400ish. Not a great ratio, but it would be the main room and that's about how I do, depending on whose sparring.
