I haven't noticed what you're describing - though I will say that I notice the difference between two different types of vape-gear whenever I switch after an absence.
For instance, I will often use an RBA almost all day, then go to a carto-tank while running some errands - and initially the difference will stand out. But it's not that the carto is different from sitting, it's that my taste has acclimated to a different temperature, wick, vapor volume, etc...
At any rate, I also should mention that I've been getting VERY good life out of Boge cartos lately under these conditions. Meaning, I might use it for an hour a day, IF that. And it keeps going and going. I expected them to "age" more rapidly - with a clock ticking as soon as it's wet. And maybe it does - but not quickly. They're lasting a month or so...
