Why is opponent connectivity critical to eliminating regional rating inflation? | Dink Digest Knowledge Base

Q: Why is opponent connectivity critical to eliminating regional rating inflation?

Without matches against players from other geographic regions, isolated club communities develop inflated or deflated rating bubbles. If a group of 20 players in a rural town only play among themselves, their internal DUPR ratings will diverge from national standards. When one player travels to a national tournament in Phoenix or Dallas and plays against connected national players, their rating adjusts, acting as a 'bridge node' that mathematically recalibrates the entire home club cluster.
