SOLVED: Glitch in the eFTP calculations

Bug Reports
1

Long story short - Haven’t been training for a long time (on and of 18 months)
In first block back. Getting eFTP notifications now too.

First off, I know these are only estimates. I know the numbers given are not reflective of actual FTP. I know that the model can only estimate based on the data it’s given. And I know I haven’t fed it a full range of data. Nor will I be doing anytime soon.

All that said, there is a definite bug in the estimations as I see it.

Tuesday April 21st I did a 20/15/10 session and was given an estimated FTP of 235w. This was based off “FTP +29 to 235w from 25m at 242w”

So it has established now that I can at least do 25 minutes at 242 watts.

Roll on to Saturday April 25th where I did a different session. 20min tempo blocks.
After this I got “FTP +5 to 216w from 20m at 228w”

So on the Tuesday I was given an eFTP of 242w but on the following Saturday I was told my FTP was increasing +5 to 216w. Clearly something not quite right with the matrix there!

I don’t pay any heed to these estimations. Like I said already, garbage in, garbage out. But this is clearly a bug which I thought I’d report in case anyone does use this feature and want more accurate results.

@david - fell free to look through my data if you need to. I have no issues with that.

As long as you don’t ‘accept’ the new FTP, the former one will stay in place.

Ah! That makes sense. Thanks.

While this doesn’t answer your original post, it’s related to eFTP, and perhaps some more.

If you want your FTP automatically updated to match your eFTP, I have an app linked to Intervals that will do it, based on a few settings (daily, when it changes by more than the daily variance tolerance, or never).

While I don’t use it, it’s there for people that want it. It’s configurable in the settings, as a once off and forget.

Look for BaieSukkel AutoMate in the Apps section of Settings page. No username and password required, as it only gets/updates data from your Intervals account.

The core principle is automating certain data fields and phone notifications to close out missing data important to you.
