Different TSS and IF between Garmin and TR

What I’m missing here? The ftp is set the same but IF and TSS are different.

Hm Garmin is fucking up, but why? :man_facepalming:

max power is different so I’d guess there are other variances in the file…

Ok, so I noticed this again today. It has been the same almost all the rides.

Downloaded the files from TR and from Garmin and added them to DCrainmakers analyzer.
https://analyze.dcrainmaker.com/#/public/0618bd81-8d17-4c03-7b24-938d58195576
And the files seem to be close together.
So any ideas why other gives IF 0.94 and 0.957
TSS is also bit different.
