Today is 14 Oct 2025
On my power chart, the last 42 days range line covers 2 Sep 2025 to 14 Oct 2025
On my compare power to HR chart, the last 42 days range line covers 3 Sep 2025 to 14 Oct 2025
Am I doing something wrong when setting up those lines?
Something looks off there 
On the overall Power page, mine gives 1Sept - 13 October (no activity today yet), but that’s 43 days… if both start and end date are included?
On the activity Power page, it’s backwards from the day of that activity, also 43 days.
On the compare chart, it’s calendar days, today included, and effectively 42 days (Sept 3 - Oct 14).
I guess the Power page should take the last activity and then 42 days back? But it’s 43 days if both start and end are included.
A reasonable person would reasonably expect them to be the same, wouldn’t they?
I agree for the overall power page and compare chart.
But i like the way it works on the activity power tab. That gives you a clear idea of how the power was at that particular time.
On the fitness page, choosing the 42 day range also gives 3 Sep 2025 to 14 Oct 2025
I don’t really have much preference and I will sleep soundly tonight even knowing of this discrepancy, but I do think it would be better if the 42 day range on any chart was consistent with all other charts.
