Months without a mean, and why
1 month
| Month | Why |
|---|---|
| Jun 2025 | 18 of 30 days measured; a month needs 21. The others: 9 with no readings from the monitor, 3 with readings for part of the day (a day needs 18 hours). |
A day counts once 18 hours of it are measured; a month needs 70% of its days.
