Very interesting, making me wonder all the more exactly what fitness/freshness is actually indicating. I'm at best a high-end Cat 5. As of last month my FTP was approx. 245 as measured separately by both Kickr and on-bike power meter, putting my P/W somewhere around 2.9 to 3.0.
Below is a (lousy) snip of F/F over the last six months. F/F increased steadily from March through July, peaking in the area of 110 through July. I do think you are correct though, I probably overreached. I was feeling pretty burned out which was why I was glad for the easier workload through August.
