How to Improve Your UTR
You have 1 win against higher-rated opponents (up to +1.3 UTR above you). These are the biggest positive contributors to your rating. Your recent form has been difficult. UTR weights recent results more heavily, so turning around your next few matches will have an outsized positive effect.
