here is the problem as I see it, the dP vs. Q curves cannot be (well) made w/o a bunch of quality equip
one could postulate a lesser 'grade' of equip, and guarantee shit results (been there, done that Thanks)
this type of testing is not, to me, the reasonable province of typical review sites

no reason not to collect and 'bank' the data

good reason to question data, look at that cal thread - and I am STILL in the middle of all that
