When I review my activities, Garmin 935 time in HR zones adds-up less than the total activity time. Regardless of wearing an external HR or not. As an example, this morning I did a 50:40 minute run, but time in zones shows:
44:14 Z1 and 00:53 Z2, which adds up just 45:07
Another example, this time a bike ride, gives me the following:
| ZONE | POWER | HR |
| Z1 | 0:54:35 | 1:20:01 |
| Z2 | 0:35:54 | 0:37:28 |
| Z3 | 0:17:55 | 0:01:45 |
| Z4 | 0:17:45 | 0:00:00 |
| Z5 | 0:05:12 | 0:00:00 |
| Z6 | 0:03:33 | NA |
| Z7 | 0:00:54 | NA |
| TOTAL | 2:15:48 | 1:59:14 |
As can be seen, power zones add-up, but HR zones do not, unless my pulse stopped for over 15 minutes ;-)
Is this a reported bug being fixed, or am I missing something?
