ATR 72: you match torque...and the synchronizer does that as well. Never heard of matching ITT. I've seen engines 20 degrees different from each other with the same torque, rpm and nearly same fuel flow.
Since ITT is of little use of an indication of true power I can't see why you'd match it.
I think I would've asked (liked I was totally clueless) what the reasoning behind that was... you would've probably had the answer in excruciating detail.
