Hi,
Saw couple of threads about it for earlier software versions, apparently still exists on 12.27.
Today's instance: Cycling, live during activity was aerobic 4.3, anaerobic 3.2.
After saving, already on the watch in the summary screen showed aerobic 3.8 & anaerobic 2.4.
Exercise load was the same though.
Needless to say for some scenarios I find following effect in real time extremely important and influence when I'll stop.
The deviations I've experienced today are pretty substantial IMHO.
Thanks,
