I recently tested the 245 and the Stryd, and it would always show pace rounded to 5 seconds, for example 4:15, 4:20, 4:25, 5:00, etc. but never 4:13, 4:21, 4:27, 5:01.
My outdated Polar M400 just showed the exact, unrounded number, which I prefer.
Also, it seems to update the numbers with a delay, after increasing the tempo it takes some seconds until I can see the faster pace. Again, on my Polar, the numbers seemed to be updated more quickly.
Is there a way to fix this issue? I do like the Garmin a lot more otherwise, way lighter, better looking and more comfortable to wear than the M400.
