I have a great deal of time on the A++ and have worked for 3 companies flying them. We always matched what ever would reach limits first at take off and matched torques during cruise.
I Agree with DK that there is really no reason for matching Fuel Flows. Given the reliabilty levels ( or lack there of ) of the Fuel Flow Indicators I see Very Little Merit In Teaching Line Guys To Match Them!
I guess at the end of the day we operate to what the company that pays our cheque wants us to do.
