    Look at the plot above. FTP will be essentially the same as "1 hr avg watts." Notice how well it's correlated with VO2 @ LT. Now look at how well VO2@LT is correlated with VO2Max.

    Ah. MMP is Max Mean Power over different durations. W' is what people used to call AWC, or anaerobic work capacity. Monod's model is that Work (in joules) = W' + CP * t where t is in seconds. There...
