Greg, would it be possible for me to send all my posts to you for
checking of units first? :)

Isn't this just a matter of instrumentation, not the blower?  If
I have an accurate means for measuring flow and a good manometer,
I would think that my means for generating the flow is of no
consequence.  Now, of course, if I plan to use blower motor current
or some similar parameter as the means for measuring flow, then all
bets are off, as you indicate.
