Training-load capture gap

Event-gated load tracking (Garmin: load accrues only during detected workouts, sensor power raised only then) loses data permanently on a missed or self-ended detection — dc-rainmaker's mountain ride ended itself mid-descent and the remaining intervals vanished from training load with no way to recover them. Continuous 24/7 load models (Whoop strain, Fitbit cardio load) cannot miss. A core architecture split in fitness wearables; Garmin's likely fix is holding high-rate HR recording longer after detected activity ends.
