The EVO doesn't produce dark ABV. This was discussed earlier, I believe... probably a hundred pages ago... anyway, as there is minimal conduction, mostly convection, the "browning" effect is missing. ABV is pretty spent while still yellowish/straw/tannish.
Go by how it hits, tastes, and medicates, not by what it looks like.
This was my experience as a rookie EVO user, but with a short bit of time, I was pumping out some pretty dark ABV. Not sure if @lazylathe is around this thread anymore, but that was my chief complaint. Things changed fast, and I was getting darker ABV than he was. A factor may also be where your starting point of moisture in the bud is as well.
With respect to convection/conduction.....and having the browning effect missing, it's definitely not my experience, and my Cloud+ proves this even more....I can get it as brown as I want. I personally think the EVO just doesn't get as hot as the older Clouds did period. It's probably a good thing because the EVO can get absurdly hot, and I HAVE burnt my hand before on it.
