The table of estimated zMAP and zFTP is hidden my default. The numbers are innacurate for most riders. I've found examples where riders that are 20watts stronger in the 20m-50m range have the same zFTP as weaker riders. I raised my own power throughout the 2m-7m range, and my zMAP went down according to Zwift. I even fed data for 2000 riders into a machine-learning algorithm and it couldn't predict zFTP or zMAP within 0.2w/kg accuracy on average. I don't know what Zwift is doing to come up with these numbers, but it doesn't make much sense, and doesn't seem consistnt between riders. So this table is hidden unless enabled with the understanding that it might be quite inaccurate by 10watts or more.

By default Sauce uses your Zwift-reported FTP as your Critical power, and a W' of 20kJ. Normally you can manually update any rider's CP and W', and Sauce will store it in its local database to use instead. This mod can use your 90-day power curve to calculate the CP and W' and update Sauce instead of you having to update riders manually. (at the moment, the calculation used seems to have a low W', so expect to see people's W'bal become negative if enabling this.)
