Threshold calculations

Since the firmware update that automatically updates lactate threshold and running ftp, I've noticed a couple of things.

My lactate threshold increased from 141 bpm to 148 and running ftp from 343W to 345W. I use the running ftp value in trainingpeaks and I got the initial value from a manual test wearing the 965..

What I find curious is that according to connect my lactate threshold of 148 is equivalent to a running power level of 342W, three watts below what Garmin calceolate for running power ftp.

So, which value for running ftp should I use in training peaks: 345 or 342?

Thanks

This is less than 1% difference. Don't worry about it. The average standard error of the Garmin training metrics (VO2, VO2Max, EPOC, and therefore their derivatives like training load, etc.) is typically the 5-10% range.

Thanks - probably overthinking it!
