When viewing the Analysis of a run, it would be nice to see Pa:Hr and Pw:Hr ratios if an HRM and/or power pod were used.

For example, in this run (zipped TCX activity), I wore my Stryd foot pod, so it shows my Pw:Hr value. I would also be interested in seeing Pa:Hr (pace) without needing to calculate it manually. However, because I wore my Stryd, the Pa:Hr ratio is not available:

According to that run, my Pw:Hr = 1.4%. However, my Pa:Hr is:

firstHalf = (8 × 60 + 36) ÷ 143
secondHalf = (8 × 60 + 32) ÷ 147
100 × (fistHalf - secondHalf) / firstHalf ~= 3.5%

Pa:Hr = 3.5% while Pw:Hr = 1.4%. Pa:Hr indicates I'm at my aerobic threshold while Pw:Hr indicates I'm beneath it:

3.5–5 percent: You have determined your AeT heart rate, which was your starting heart rate for the test. Set that as the top of Zone 2 in your TrainingPeaks zones. Subtract 10 percent from this and set that as the top of your Zone 1.

0–3.5 percent: The workout was within your aerobic intensity zones, but you should do the test again at a starting heart rate that is 5 beats per minute (bpm) higher.

>5 percent: Your initial heart rate/pace was above AeT. Redo the test using a lower starting heart rate. It may take several attempts to nail a decoupling that is slightly less than or equal to 5 percent.

So, displaying strictly Pw:Hr might be misleading. At least as a Stryd user. Maybe the power meter in newer watches, such as Garmin, Coros, Wahoo, Suunto, etc. might give different power readings, and as a result, different Pw:Hr percentages.

Anyway, it would be great to see both pace and power aerobic decoupling, or toggle between them.
