Find interval used to calculate Ride eFTP

Is it possible to see which interval in a ride is used to calculate/estimate the effective Ride FTP ? I saw on the boards the ‘best’ interval is used, but in practice a lot of rides have many intervals with different durations, and it is not easy to see which interval is the ‘best’ and which one is used to calculate Ride eFTP

Perhaps it is possible to add functionality that if you click the Ride eFTP it says ‘Based on the interval 287W @ 37mins the Ride eFTP is set to 275W’ ?

I added that. Good idea. Tx.

Awesome david! and super-fast as well!

Similar question… is it possible to see which ride produced the eFTP? Mine shows a value which is way too high, so I’m curious which ride I did it on.

Thanks!

Go to the /fitness page and look for little solid red dots at the bottom of the fitness/fatigue curves. These are “FTP UP” and other achievements. In your last select the last year and you will see some around Sat 12th March 2022.

ahh got it! How do I disregard that ride for calculation purposes? My power meter had gone out of calibration and was reading at least 15% too high

Go to Actions → Settings on the timeline chart and chose “Ignore power data”:

You could also scale the power data down using Actions → Fix data.

Thanks!

Hi, is it possible to see where in the activity this interval is? as in, at what timestamp it starts for example. Given that you already show the duration of the effort, I can add it to start timestamp to find the interval.

out of curiosity too, does this calculation take into account auto pausing of my garmin device when I stop at traffic lights for example?

It would really be beneficial to see which exact interval is used to calculate the Ride eFTP since many rides include several efforts for different lengths of time. While it states that the “best” interval is used, it can be cumbersome in practice to figure out which interval that is. If a feature was added where clicking on the Ride eFTP displayed “Based on interval 287W @ 37 mins, the Ride eFTP is 275W”, would be a lot clearer, and users would be able to interpret and analyze their performance much easier.
