I am totally frustrated by the pace calculation in my FR255. It must have some implementation errors with round offs.
Situation:
I am a European (half) Marathon runner-> pace in km / min and able to keep a constant pace here where it is really flat.
I follow the Training suggestion long run 16,1km 5:36 - 5:18 min/km. (that is already a minor frustration as these values are only derived from imperial).
And I have an autolap set at 500m, so I do get regular feedback on my pace that I can calcualte myself.
And at around Pace 5:30 I can exactly keep running in Heart Rate zone 2. So I try running with an actual pace of 5:25 - 5:35, mostly towards the slower border.
Now for vast amounts of distance, my FR is calling the 'too slow' alarm. But with pace 5:35! Easily 50 to 60 times during the 1,5 hours run.
Strange. The Coach function had the workout thresholds set on 5:36 - 5:18. So the pace is OK but I am too slow?
As pace is a rounded figure, it could be that for a really long time, I am just doing 5:37. But I hardly see Too Slow 5:40, mostly Too Slow 5:35. In itself this is pretty frustrating.
But where the watch confimrs the pace must be wrong is every lap time. Mostly my laps are betwen 2:42 and 2:45. So a pace of 5:24 to 5:30.
How on earth can that be?
My actual pace show mostly 5:30 or less. My watch is beeping I am too slow at 5:35. And then confimring I was running the last 500m at 5:25.
I have a suspicion there is a lot of rounding being done calcualting the pace. Perhaps from Imperial to metric.taking the average over some seconds and then more when comparing that average to the workout borders.
