I made a custom activity profile based on a copy of "Trail Run", which I use for trail running. The VO2 Max estimate is always pretty off after I run on rugged trails, so I'd like to turn off the relevance of this custom trail run activity for the VO2 Max calculation. The original Trail Run does this as well. I turned off "VO2Max Calculation" in the settings, but it doesn't seem to have any effect? At least, every time I use the custom activity, my VO2 Max estimate takes a huge dip. Is this a bug? All the settings look the same as in the original Trail Run profile, but the copied one doesn't get ignored for the VO2 Max.
