Hard to say how the next 3-months will go as Zwift is still very much an experiment for me, but last winter (weekly avg vol of 15 hrs with less than 10% of this work above HR zone 3) my ftp went up by ~30w using this approach.. no doubt in part due to familiarization with the test itself. On the other hand, I also dropped 8-lbs of fat so power-to-weight was the more notable "achievement". Either way, I mostly treat the 20min as a bi-monthly low tss workout to improve my cadence and ability to sustain threshold efforts without blowing up
