Score starts with MMR, then applies light strength-of-schedule, light activity/volume bonuses, and a low-games penalty.
- MMR is primary. Strength of schedule is capped at +/-300 and scaled by confidence.
- Playing more helps, but volume is intentionally limited so it does not overpower rating.
- Players under 100 games receive a low-games penalty. Rankings use raw score, and display score is scaled by 10.
