DUPR gives an unrated player a rating by using their first verifiable match results and updating from there. In practice, it starts with the scorelines, opponent ratings, and match format, then adjusts the player’s number as more results come in.

How it works

  • A new player is usually assigned an initial estimate based on early recorded results rather than a guess from sign-up alone.
  • The rating then moves up or down depending on who they played, how close the match was, and how often they compete.
  • Strong wins over higher-rated players usually move the rating up faster, while losses to lower-rated players can pull it down.
  • DUPR also distinguishes between formats and can show different rating views by format or age-based breakdowns in newer features.

For truly unrated players

If a player has no rating at all, DUPR generally needs some match data first, so the system can place them on its scale. That scale runs from 2.000 to 8.000, with the number meant to reflect current skill level based on match results.

Simple example

A player who beats a clearly stronger opponent in a close match will usually be rated higher than a player who only has weak or limited results. Over time, the rating becomes more accurate as the sample size grows.

Recent context

DUPR has also been refining how players can reassess or “reset” their ratings, with a reset program and results appearing in the app in 2026. That suggests DUPR is continuing to lean on real match outcomes as the main input for rating changes.

TL;DR: DUPR does not just invent a rating for someone with none; it builds one from real match results, then keeps adjusting it as more data comes in.
