Heck, I really don't care about all the number and variances in unit to unit. I am a tech nerd from way back when PCs and MACs didn't exist yet and I had to code Fortran on bubble cards and send them away to the school district's mainframe to get a result with errors a week later and repeat until my code worked. What I care about is what result I get on my ZMax when I get it. I won't care what the power setting is and what I am actually getting. All I will care about is finding a setting I am happy with, and having a consistent experience with different resistance devices. If the ZMax can do that for me then I will be a very happy camper indeed. I think most users would agree with me. Who cares what the numbers are. We just want a reliable PV with a consistent and satisfying experience. I agree with what another member said in the Gotvapes Alpha Thread; the manufacturer's should just do away with voltage settings and wattage settings and just have a power meter that goes from one to ten in 1/10th increments. That would work for most people and we don't need these silly arguments over vms, rvms, wattage, etc.
I couldn't agree more. In fact i've written a couple of nearly identical posts earlier on. While enthusiast level critique will exist in any hobby, most average-kind-of-guy vapers, that I believe represents the vast majority of vaping customers, simply want a power setting they can enjoy with most (if not all) of their heads. It doesn't matter to most that a meter will not agree with what the lcd setting says. And acceptance of this quirk as less than a significant flaw doesn't make one a fanboy but suggests many may simply not really care. We've all been conditioned by marketing hype to think that a 'what you set is what you get' voltage setting is the be all and end all on our pv's as though this is some million dollar piece of equipment that cannot tolerate a .01% variance of specs. Or it's life and death. Gimme a break.
The power delivery variances on the maxes really don't matter in every-day vaping enjoyment, unless of course you're emphatic upon vaping between 3-3.6 volts in which case you're looking at the wrong device. Just set the thing where it feels right and ignore the numbers. They're really not THAT important unless you're getting like double the voltage you're setting (which you're not).
Certainly Smoketech dropped the ball on this issue thinking we'd all appreciate 'more is better' rather than giving us a more accurate device. But in the end it boils down to whether such accuracy is something you're going to really need, practically speaking. Sure if given the choice I'd rather a more accurate device but having just bought a zmax, should the next version be completely accurate in its voltage settings would I run out and buy another? Nope. It just won't make any difference to me whether my lcd reads 3 or 3.7to get the same vape. Just as long as it's blue

Such accuracy may be a 'nice to have' but is certainly not a 'must have' unless you're into 'my pv is more accurate than yours' bragging rights.
As jackbox has articulated, if the maxes had power settings based on a meter or alphabetical where A is less and K is more, there really wouldn't be much of an issue. However it would give the reviewers one less thing to harp about.
