I have 2 issues with the pace while swimming
1. Last length pace (The average pace for your last completed pool length) is not displayed correctly:
The LLP is always the same for me and is 00:01 which means 1 sec/100m which is obviously mistaken and unrealistic. The problem is that this metric is not stored in the activity log (garmin connect). However i include a link for an activity (Activity) and a picture while I have paused the activity to display the problem:
Also, tested with a fenix 6, this problem doesn't exist in that watch.
2. Average pace:
While swimming the average pace displays in rounded in 5 sec intervals. So, when my pace is 2:03 the watch displays 2:05 and when is 2:02 it displays 2:00 and so on and so forth. In the activity this is displayed correctly. Also, when I press the lap key, it displays the correct pace again. I don't have a waterproof camera so I can display this problem.
