He who chases numbers on gauges and hopes for the EADI (by whatever name on whatever jet) to end up at the appropriate spot is one who loved roller-coaster rides as a child.
Far better to know by rote enough basic numbers for your particular aeroplane and then set attitude and thrust to suit the configuration and flight circumstances/requirements ... all the other numbers then, quite miraculously, fall into place, or very nearly so .. subsequent fine tuning is just that .. and the passengers and cabin crew give thanks for a competent I/F manipulator up front ...
Something along the lines of
"power (or thrust) plus attitude = performance"
comes to mind if one is into memory joggers ...
