I retested the SlitEdge and got
0.181psi @ 0.999gpm
vs.
0.15psi @ 0.96gpm by Joe
- I think perhaps Joe's pressure values are compressed
(I have a PolarFLO in the mail so we should get an insight into this matter shortly)

I think Joe is introducing a systemic error by not holding his flow rate constant
going to make it an interesting means of comparison
i.e. given a system flow rate of 1.00gpm w/o a wb,
after insertion each wb will reduce the flow by a different amount,
at which flow the dp and C/W are measured
- so then the basis of comparison for the wbs are the various differences, all wrt an initial flow rate of 1gpm
??
going to have to think more on this, is not quite clear (to me)
