Personally i never alter any settings in Proflight2000,apart from checking box "Aircraft requires long runway and altering length",i tend to leave everything else "as is" i know most of things in PF2K are disabled...
I, Respectfully, disagree. Aircraft specs do matter in when PFE decide on TOD. If for example you the Rate of climb to 1200 and set your altitude to 33000 in a short trip like 250nm and compile it. In PFE altitude adjustment section, you will see that PFE lowers your cruise altitude. And the same goes for FAF and I am talking from experience with changing these settings. When I first bought PFE, I had trouble reaching my last assigned altitude before being vectored to final until I changed my rate of decent and FAF to 11nm.
Cheers
