Your starting point comes from your official year-end NTRP, not from any third-party rating. The calibration is a fixed shift that puts our scale on the same level as NTRP.

Combo and mixed matches aren’t included. This rating is built from standard men’s and women’s league play only — combo and mixed results feed your separate combo/mixed ratings, not this one.
