I'm not sure if I've asked this before, but how do they calculate this number? I think I remember asking or looking up about it, but the latest answer or discussion I get is from years ago. Do they update their algorithm regularly, and how accurate is this number? I remember seeing the win probability stat swing wildly in a match I followed before. Not saying that the stats results need to be accurate 100%, just curious about what the difference is between a 70% win probability and a 60% one.
