Shadow-reset simulator
Replays every one of your DUPR matches since a cutoff date (default 2026-04-16, matching the most recent DUPR reset window) starting from 0% reliability and growing +5% per match. That answers "what would my rating be if DUPR rebuilt it from scratch tomorrow?" — the early matches swing hard, and reliability (and therefore swing size) catches up match-by-match.
This uses a reverse-engineered model, not official DUPR code. Treat the output
as a directional what-if estimate — the shape of the curve matters more
than the absolute number.
