The auto calculation for power zones seems wrong.
It seems to assume that you can't go above your FTP, which is false.
You will definitely go above your FTP for quite long periods of time and will need to do so to increase your FTP.
With my FTP of 210 it indicates that the top end of zone 2 is only 92 watts; I find almost impossible to pedal with so little effort. I would think the top of zone 2 should be at least 160.
I tried manually inputting my own numbers in the User Settings of my Edge 530 but it won't save them.
