Workout Execution Score

How is the execution score calculated? Is it based on the average pace of the interval (looks like 800 meters or so) that is then checked against [5:06-5:18] or is it sampled several times during the 800m interval?

It's just time in target zone divided by total time.

What is the sampling size? Every meter? So if the interval is 800 meters, then each one is checked for being on target?

4 x 5' (5:06-5:18 min/km) + 3' jog or walk.

Yes, only the specific training counts (not the 15' warm-up, and 15' cool-down).

I have also seen this error but am now using the beta 14.08 and believe it has been corrected based on my last two Garmin pace based training sessions.

FW 13.22 here. I think execution score is not accurate.

I created a tempo run workout with target pace of 5:05 to 5:15 min/km.

I ran all the time within target pace. But execution score = 67%

This is why you create a range, no? Say, if your target is 5:08, you can set a range betwenn 5:00 and 5:15

Just checked my workout. Corrected my post above.

Intensity target pace is already a range of 5:05 to 5:15 min/km.

And I am certain I run 100% of the time within this range.
