- Ship a fix and update the page's reviewed / modified date when the change is substantive.
- For significant public errors, note the correction here or on the affected page.
Not corrections
Differences between planning estimates and your real trip (weather, load, throttle) are expected variance, not calculator bugs — though we welcome feedback that improves labelled assumptions.
