Yeah, as usual, real life turns it ugly head back here and bites us where it hurts
Oh well, looks like it was just a food for thoughts here, a pity...
Good God, morons with bright (LED) ideas should be somehow kept well clear form such a calculator, I was more thinking of rather 'typical' rational setups (no elbos, crappy fans, raditors sitting just above heaters etc.) and a simulator being able to give you a different performance values based on CPU and h'ware choices.
I guess you are right that this would require some truly herculean effort of data gathering and keeping it contanstly upd to date as new stuff is being released quite often these days (how to get all the equioment samples to get minor loss coefficient figures?).
Cheers for taking time to write all this
