Antoine,
Your point (2) is correct. The curve fit does not need MOO values but if we are rerunning our fit to improve our first approximation of LAN, then MOO corrections for the vessel's motion need to be applied to the origional Ho set before rerunning the curve fit on the updated Time/Ho (or Time/Hs) set.
Depending on the course and Zn's you will get different MOO corrections.
But I sense I'm missing something in your note and Tony's
