Browsing through my fitness I saw this line, seems odd. I could imagine the FTP increase from 5m at 293W but not from 22m at 227
FTP +8 to 238w from 22m at 227w 1s 861w 5s 799w 60s 477w 5m 293w
And another odd entry
FTP +11 to 242w from 20m at 198w 5m 297w
5 min is the default for the eFTP minimum duration calculation. It might be a bit aggressive, but is based on power curve data. You can increase it (and many people do) to something higher like 8 min to get better calculations for the type of rides you do.
I get that my point is that 22m at 227W could never equate to an FTP of 238 and an eFTP of 242 from 20m at 198 is even stranger!
Hmm. The ramp test one has sorted itself out: FTP +11 to 242w from 6m30s at 287w
The first one has actually used a much shorter duration (10m or less) to give you a new eFTP not the time reported in the note. I will have a look and see if I can figure out why.
