Yep.
GC's CP curve is higher than my FTP too. It's better if I do a short (3 min) and long (20min) all out interval on days that are reasonably close and use the calculate CP feature. But even then it's higher than best 20 min * .95. That's because CP only uses two points. So if the 3 min one is low, it'll show a high FTP. I don't do many 3 min intervals and my aerobic work capacity is not that good. Having a poor AWC shouldn't make your FTP higher.
