I'm afraid, most of the people, doing FTP-tests, can not calculate regression lines etc., but my beta (preprepre alpha :) ) version google sheet do everything for me. I just have to put watt data, SmO2, tHb and tell what time the ramp started and it says the FTP.<br />This automation allowed me to check how it works with pure SmO2 data! Almost the same result! Maybe harder to find the break in that case, but if you do it automatically, it will give the same result. In my case it was the same second where i found the regression breakpoint.<br />I cant tell you how much you helped me!!! Thank you very much!<br /><br />ps: The truth is that Humon's Garmin data field (interval) gave me almost the same result. It became red 20 seconds before my script found my threshold! I'm going to test it with a few other guys (and girls) with different levels of fitness.Peterhttps://www.blogger.com/profile/13507061562516277149noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-40837246436024393432021-02-25T08:21:16.597-08:002021-02-25T08:21:16.597-08:00Great to hear it works for you.

The new smart trainers are the way to go.BJRMDhttps://www.blogger.com/profile/03840322337577591292noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-28867362675640788522021-02-25T08:07:42.257-08:002021-02-25T08:07:42.257-08:00Well...

I found that easier to find the breakpoint if i don't use 10seconds average. I think my trainer is stable enough to get more useful data without smoothing them.Peterhttps://www.blogger.com/profile/13507061562516277149noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-5750051068794697372021-02-25T00:43:10.820-08:002021-02-25T00:43:10.820-08:00Oh, I see!

Still it should be good enough for our purposes. If you have a smart trainer and Zwift, you can now setup a custom incremental ramp that will be much smoother.BJRMDhttps://www.blogger.com/profile/03840322337577591292noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-37085366814373352021-02-24T14:53:53.134-08:002021-02-24T14:53:53.134-08:00Another thing which is not clear: you said start p...Another thing which is not clear: you said start pedaling at 100W and increase 30W / 3 minute. And .... your data shows 118W at 10 seconds, 142W at 20 seconds and so on 143W at 180s. :o you should have kept 100W for the first 180s. At 950s you should have been at 100 + 5x30 = 250W, but you wrote 280-290...<br />Could you help me to understand this part?Peterhttps://www.blogger.com/profile/13507061562516277149noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-87041959896263520672021-02-24T03:02:25.687-08:002021-02-24T03:02:25.687-08:00Thanks!

I hope it will be useful to find the breakpoint in the least subjective way.<br />There is a moxzones app which promises that it can find LT2, but I haven't tried it yet and "noone" is using it on the internet.Peterhttps://www.blogger.com/profile/13507061562516277149noreply@blogger.comtag:blogger.com,1999:blog-5699699130631903971.post-30520874157421878962021-02-23T12:00:54.839-08:002021-02-23T12:00:54.839-08:00Yes, I do.

If you have an older BSX or Humon give it a go.
