I would be obliged if someone could help me in understanding the torque tables of ATR 72-500 (I assume that other types have similar docs).

The Max Cruise Torque tables in FCOM (section 3.02.02) have different referenced IAS per page. Considering that these tables are supposed to give the FDAU setting for max power, how the IAS is relevant"
How these tables relate to Max Cruise tables in 3.05.02 ? In these tables, weight is the main parameter, while in Max Cruise Torque tables weight was not referred. Does this mean that weight has only to do with achieved IAS and fuel flow per case?
In Max Cruise tables (3.05.02), tq seem to fall beneath 94.5 (engine mechanical limit) at lower altitudes than in Max Cruise torque tables (3.02.02).
It is quite frequent that the FDAU setting at CRZ is somewhat higher than at
CLB (same altitude). How can this be explained ?

As said at the beginning, if anyone can spare the time, would be warmly appreciated.
