OK. I find that my 1 min power is really strong, and I find it tough to hold a long effort. I too struggle with sweet spot and do well in VO2 Max. I need to backpedal quite often during Sweet Spot efforts.
In absence of newer TR data, I am attaching my 4DP test data. This is after SSB LV1 and SSB LV2. I have been detraining past 2 weeks due to life getting in the way, but here are the numbers:
5 second (Neuromuscular Power): 603W (valid)
1 minute (Anaerobic Capacity): 337W (valid)
5 minute (Maximal Aerobic Power): 236W (valid)
20 minute (Functional Threshold Power): 175W (valid)
