Track the gap between misses, not a perfect streak

Watch for consecutive misses rather than chasing an unbroken run.

Why it works

A perfect-streak tracker punishes the first miss and triggers the very all-or-nothing collapse the two-day rule avoids. Tracking the gap between misses instead makes the meaningful signal — two in a row — visible while treating isolated misses as normal. The feedback you watch shapes the behavior; watching the gap reinforces resilience rather than fragile perfection.

How to do it

1. Record each day as done or missed, but make "two misses in a row" the alert, not "any miss."
2. Glance at the record to see whether your last miss was yesterday — the only question that matters.
3. Let isolated misses sit in the record without erasing your sense of progress.

Evidence

Grounded in self-monitoring research (tracking improves adherence) combined with the habit finding that isolated misses are tolerable. Tracking the gap rather than the streak is a practitioner adaptation that aligns the feedback with the rule. (mechanistic)

Tracking the gap reduces perfectionism but still requires honest logging; a record you ignore provides no signal.

Common mistake

Using a perfect-streak counter that resets to zero on the first miss, reintroducing the brittle all-or-nothing pressure the two-day rule was meant to remove.
