Even that presumes you have hit max at the different CP numbers. If you've got a lot of race/TT/test data you can usually get a pretty good handle on this.
I think SpongeDad was talking about the published power curve for the KK trainer, but I see your point. In any case, I am content with feeling my way along for now using approximate correlations. My feeling is that it's easy to get way too caught up in the numbers. It's nice to know my FTP, but I don't feel I need to know it to the watt. I need to know it well enough to set my training zones. I tend to race on feel anyway.
FWIW, I use golden cheetah, which calculates a CP based on historical data, but I don't use that number. I have a pretty good feel for what I can do for an hour and that is probably more accurate than some blind, 2-point correlation model.
