I have recently started using the training workouts feature to run interval workouts. Depending on the workout, I might do 5 minutes in zone 2 followed by 5 minutes in zone 3, followed by repeated Zone 4/Zone 2 intervals. The stats afterwards though, group certain segments together. The best I can figure out is that it combines the stats for any successive steps with the same type (e.g. "Run", "Recover"), and between successive "Other" and "Run" step types.
The screen shots show a mixed interval run with 5 minutes warm up, 5 minutes "Other" (at a slightly higher heart rate), then a series of repeats starting with a 1 1/2 minute sprint. The resulting stats however, show a 5 minute warm up, followed by 6 1/2 minute run. i.e. steps 2 and 3 were combined.
Is this a known bug, or am I doing something wrong?
