FTP Drop After Base & a Break - Accept, Reject, or Average?

Based on the workouts at 207 were doable albeit challenging. Seems like a fairly large drop but maybe I’m just not informed, as I mentioned this is a bit new to me.

The 174 was around what my FTP was before a summer of riding. Just seems odd that I’d fall all the way back to my starting level in 3 weeks.

Again, this is new to me so why I’m asking.
