I don't have much concern for what planes changes how (I have confidence it will be fairly realistic, which is all I would want). Any apparent stressed concern is just keen passion to think about the topic (and combined with an excessive verbosity = long posts).
Curious I am to learn more. Here I go thinking I had a decent understanding of how aircraft behaved in some aspects and things like these come along to stir the pot.
May have a look around for official figures for some of the aircraft.
