Yeah, so to answer your original question - no idea. I don't know how the output from whatever translates into FTP in Training Peaks. It looks like the build up to the event was harder than they event which makes me wonder why. Either the training was too hard or you rode the 'race' poorly. This could be because you didn't fully recover from the large week beforehand. This is why people build up slowly to their peak events - you can't just smash it the week before and expect to be recovered and fast unless you've got a good handle on your recovery ability and/or can afford to sleep all week.
