I'm a new FR 265 owner, upgraded from a Vivoactive 4 a few weeks ago. My primary aerobic workout is swimming laps indoors in a 25 yard pool.
The issue I'm having is that occasionally, for no reason I can figure out, the watch will split an interval into parts. For instance, during my last swim, I was doing a 1000 yd interval, and at some point in the middle, I looked at the watch and it said I had done 550 yards - I felt like I'd done more than that, but I lose track a lot - which is why I have a watch to track distances LOL Anyway, when I got to the end and entered a rest period, I scrolled down the stats screens and lo and behold, the watch showed the total distance covered as 1100 yards; It had started a new interval after 100 yards which I did not notice while swimming. Note: The total time was correct, and upon review afterwards, there's just two consecutive intervals with no rest break in between. I've done 4 swims with this watch so far, and this has happened during 3 of them, with the breaks happening at 350 yards, 150 yards, 50 yards twice, and 100 yards - i.e. nothing consistent.
Is anyone else experiencing this? Is there a sensitivity setting or something that can be tweaked to stop this from happening?
Other than this irritating issue, I love this watch - it is a massive upgrade over my Vivoactive 4 
Thanks,
Andy
