Hello! Tom, thanks for the detailed answer. The mathematical meaning of your proposed calculation is clear to me, the algorithm for the proposal to improve power for 5 minutes is also clear, but there are details that are incomprehensible to me. In the race on July 8th with a current weight of 101 kg, I improved my times by 5 and 15 minutes at the same time and received a message about the change in FTP from 332 to 333. Based on the results of the race, the category was upgraded to B.

All the best results of 5, 15 seconds and 10, 20, 30, 40 minutes were achieved in June with a weight of 100 kg . After the race on June 26th I received a message that my FTP had changed from 323 to 332. Group C was unchanged.

Results earlier for 30 seconds, 1, 3 minutes in April and May and after for 5 and 15 minutes in July were achieved with a weight of 101 kg.

I’m trying to understand the mathematical logic of transferring to group B. I would be grateful for your thoughts on this topic.
