About 75% of the time when going out on a run the hr my 970 shows is as much as 20-30bpm too high. Normally within .5mi it straightens itself out and starts showing the correct hr.
This isn't the normal issue with Garmins where the hrm is wonky when it's cold outside. I'm used to that.
This week though it didn't straighten out until I was on my third mile! And that was after stopping the run multiple times and restarting the watch!
Anyone else seen this issue?
