@THH, I have a question for you from a theme that seems to be popping up now and again after reading your posts. At multiple times you mentioned possible discrepancy about input power measurement of Mizuno not clear if its measured before or after the PSU. Yes, I agree it would be nice if input was measured after the PSU but 100% of all PSU's have a finite efficiency so even if it was measured at the line voltage outlet level, that would over-estimate (not under-estimate) the input power unless you think the PSU efficiency is over 100%. So, yes I agree that these things should be cleared up but in terms of any possible error that would under-estimate input power, this one is a non-starter. Can we agree upon that in principle? As Jed says, there is nothing easier to measure than input power.
In terms of the flow velocity profile, if Paradigmnoia is having problems with mixing, I suggest stuffing a high-porosity sponge filter like what you can buy at K&N, etc. that will remove any vortices, etc. from the fan before the air enters the tube. These would have minimal pressure loss and should solve most of these profile issues being discussed.
Daniel, i would agree with you but for two issues:
I) Mizuno has corrected data based on efficiency etc and not documented that. So we'd need to verify whether this was done with the power input, because it would be easy to do it wrong.
2) the problem is inconsistent measurement. For example measuring calibration input before the PSU could lead to lower calibration power than active power if this is measured after. It sounds silly, should not happen, but the evidence from the 2017 spreadsheet indicates that it might happen.
A lot of my finickyness here is that the methodology is not in this case not entirely trustable, and not clearly reported (ok - perhaps if reported with all data calculations it would be trustable and the things we don't understand would all be understood) - so I want to find as many independent cross-checks as possible.
