What kind of PMI reg did you use? Was it a PSI PMI, a Chinese version of the PSI PMI, or the newer Reactor? Also, what did you do with each reg? I mean, were they brand new, put on a tank and off you went? Were they donated by other local users, so there is no telling how much use they have had? If it was the second, were they cleaned and lubed before your test, or left as they were?
Good test, I guess. Something else that you can do, that would be easily enough to check, would be show the output pressure of each tank, at various pressures. Such as show when the tanks are filled at 4500 PSI, and then what each output pressure is as the tank is emptied. you can do 100 PSI intervals, or maybe 500 PSI intervals. As I understand, each reg will actually drop in pressure output as the tank pressure drops, and I have heard that in can drop a couple of hundred PSI over the typical usage of the tank.
I actually have had a similar idea as doing that last test, but with my $5 (Retail) small gauges that you find on the tanks and can get for other equipment (I just got a 1200 PSI gauge), I am pretty sure that you guys are going to get a better reading than I will.
By the look of that data sheet I'd say that Ninja is 1st with Crossfire at a close 2nd.
I may be reading the graph and spreadsheet wrong, but I would say that the Myth is actually a more accurate 2nd, with the Crossfire being a very close 3rd to the Myth. Afterall, the Ninja stayed at the output pressure the whole five minutes. The Myth started at it's pressure, raised up 10 PSI after the first 30 seconds, stayed there for 30 seconds, then settled back down to 700 PSI for the remainder of the time. The Crossfire started at 780 PSI, raised up to about 790 PSI after 30 seconds, then raised up to 800 PSI, until the last minute, when it raised up to 810 PSI, and stayed there until the end.
I know that CP thinks that Myths are junk, but how about a video showing the outputs of the other regs? It is easy to slew others opinions if you only show one reg having the 160 PSI variance, and now show the others being more consistent, if that is what you are trying to claim.
*EDIT* I misspoke, the Dye would actually be a close 3rd place and the Crossfire being in 4th place. The Dye reg raised up 20 PSI in the first 30 seconds, and then stayed there.
