How it works
The tracker records per-level splits and projects your final time against the live world record (Chapter 1 Any% WR: 2658s). The Breakthrough eligibility indicator turns YES when your projected finish beats the WR. The John Elsewhere indicator turns Feasible when the full-game projection is mathematically survivable (no death count tracked here — speedrun split tracker only).
LocalStorage persistence
Split data is cached locally so an accidental refresh does not erase your run.
