Winrate unfortunately is a pretty useless metric. In a ranking system like this, you basically progress until you hit ~50% win rate. You'd get the same win rate whether you are in Bronze or champion. Over time, every account and every bot service will get to around 50% (if it was higher, you'd go up in ranks until it dropped back down to there). So I show my win rate mostly to show that it did as expected, but win rate itself is not really an outcome of interest.
