A couple of weeks ago I finished the All Purpose plan, and rounded off with an FF. I was a bit disappointed to see my FTP reduced by 25 W and my MAP reduced by 18 W from the mid plan HM. Although the second part of the plan was not executed 100% according to plan, consistency was still maintained.
Although being Time Triallist rider type, I think maybe I do better in HM than FF despite what @Coach.Mac.C states in the beginning of the thread. At least based on my latest attempts it feels I have a slight underperformance on FF, and perhaps a bit too well in HM, thus, the actual numbers may perhaps be somewhere in between.
Worth noting perhaps, is that my heart rate seems to have increased post-vaccination. In the months immidiately after I especially seemed to struggle, especially at MAP intensities, with a far higher HR than pre-vaccination. I suppose it has kind of levelled out eventually, but it is still notably more challenging with MAP efforts than before and I note my LTHR has increased a couple of beats compared to pre-vaccination (perhaps an insignificant change?).
Anyways, It feels like my current FF numbers are somewhat on the easy side, whereas my previous HM numbers were slightly on the challenging side.
I am inclined to do a new HM as a kind of second opinion, and if there is great discrepancy from FF I am inclined to manually change FTP and MAP to somewhere in between based on my own best judgement.
Both the thought of training at too low intensities, as well as too high intensities, makes me worry.
