Hello,

for running workouts, the efficiency factor calculation for me uses m/s for the pace divided by heart rate.

Due the values for these metrics, the EF is a rather small value somewhere around 0.02 which ends up being a rounded value and would require an increase of around 50% to show a change.

I would request that you multiply the result of the calculation pace (in m/s) / heartrate by factor 100.

This would allow to actually see smaller improvements of this metric.

As an example right now:
Pace of 2.5m/s (which is around 6min/km) and a heartrate of 140:
2.5 / 140 = 0.0178 which is rounded up to 0.02

Now let's say I improve that to a pace of 2.75m/s at same heartrate (a 10% improvement!)

2.75 / 140 = 0.0196 which rounds up to 0.02

I would need A massive improvement to see any change in this metric with the current calculation used.

Can you please improve this?

It would be great to track EF for cycling and running with power, so that you can see trends with respect to power output and HR over time. It would be useful to see trends as well as sudden shifts that may result from acute issues (illness, injury, overtraining, etc.).

much like the performance management chart and several of the others i'd like to see a chart that plots pw:hr and ef

The ideal would be a scatter plot with individual workouts with a 7-day and 28 or 30d average overlayed. Tracking this along with resting HR, HRV, and perceived fatigue and effort could be a great quick and obvious way to track the body's response to training and acute increases in stress, sympathetic overactivity, and CNS suppression.

And cycling too!
