Grade Adjusted Pace (GAP): raw pace corrected for elevation using the Minetti effort curve — makes hilly and flat runs comparable. |
HR Filtering: first 10 min, last 3 min, and any period where HR is changing faster than 0.2 bpm/sec are excluded from pace@HR calculations. |
GAP@125/150: requires 60+ steady seconds in the 120–130 / 145–155 bpm window. Shows N/A if insufficient clean data. |
Decoupling: <5% efficient · 5–8% moderate · >8% high drift.
