Yeah I've found the Coggan chart only reliable for steady state stuff really. In races I've had disappointing results (which is nearly every race I've ever done) I've often thought i could have hung in there fine on 10% less at ftp and if i could have swapped that for 20% more on my 20-30s sprint I'd have done better
My Coggans chart numbers generally suck (mediocre 3rd cat according to it) but I'll score points fairly consistently in E12 crits and podium 2/3s. Good short power and repeatabilility goes a long way...
