Is Beating Someone 165 Points Higher a Big Deal?


In general, your win rate v +165 rating is somewhere in the neighborhood of 25%, so it's uncommon but not unseen.
You might have heard this before, but given your level of ~800 rapid, I wouldn't advise playing a lot of bullet games. I'm a person who plays bullet frequently myself, but I really don't think it will be the best for your improvement.
