I'm with mattm and valygrl. The only data that is accurate is the raw power. All metrics are suspect due to the estimated FTP. I would draw no conclusions from them. However your training cycles are very valid data. To rest for weeks doing nothing then blast, rest, blast, rest, burn is no way to train for consistency my friend. You need a little structure. Even Fudgy the Wunderkind trains with some kind of structure. You don't need a coach, you need a plan. A coach can help with that, or you can parlay the free advice here and devise your own.

My my suggestion would be to take at least one week completely off with no strenuous activity, long periods of standing, etc. Then start a base program at a low weekly TSS. If you go on a group ride or solo ride on the weekend keep the hard stuff for that but minimize it during the week. Focus on tempo, a little threshold, and recovery rides. As it gets towards the holidays the start ramping up the intensity and adding in rest weeks.
