Do you think your VO2Max is still improving at your level (whatever you may do and whenever you may do it)?
You bring up a very important point-what is the real value of raising one's VO2max number?
I suppose my VO2max number is going up slightly, but that is not an objective. My power at VO2max is important, but what's more important is how well I can handle 450 watts, or 550w, or 700w, etc., and how long can I sustain high power in that range of intensity. Ultimately the goal is how well I can handle the requirements of races, and for the types of races I focus on the race results are determined mostly when the intensity level is well above my power at VO2max, i.e. last 2 k's of a criterium, points race sprint laps and attacks, etc.
So whether my VO2max number has gone up 10% or 15% doesn't interest me for more than entertainment. What's more important is how fast I can go when the race outcome is being decided.
This is why my VO2max training intervals aren't soley intended to raise my VO2max, or increase the time I can ride at my VO2max. If that were the case I wouldn't do the intervals much above 150% of LT power (because that's probably the upper limit for the most effective way to increase the VO2max number). By the time I get near peak I'll be using targets around 200% of LT power for the 30/30 and 40/20 on/off intervals because being good in those power ranges is part of what's needed to get the job done. Other guys do this too, and some track races amount to essentially the same kind of training, especially Madisons.
