UTR currently recalculates daily - there can be a variety of reasons why a change (up or down) would occur. Some of these reasons could include:
- You played a player that was unrated/projected and their rating has become more reliable through more play
- Ratings are calculated every day using the current ratings of the opponents. So changes in their ratings can have an impact on your UTR as well.
- Scores from more than 12 months ago fell off your record
Remember, UTR is a measurement of player skill today.
