Worth noting some of the changes being made to VO2 intervals by Chad, [over on this thread](https://www.trainerroad.com/forumt/plan-improvements-short-general-and-sustained-build/8413) - especially on sustained power build with workouts like Shortoff +4 and Monadnock +4.

General trend is an increase in recovery interval duration, as the conclusion from data seems to be that 3 minutes isn’t enough to recover from 3 minutes @ 120%. Which I can attest from previous attempts at Shortoff +4 was damn close to impossible.
