It's probably a display preference more than anything. I once owned a Mercedes that was never intended for the US market and the speedometer had KM/H and no MPH and it was a really hard transition for me to wrap my head around. For quite a while I drove around well below the speed limit as I guessed how many MPH I was actually going. I eventually worked my way through all the conversions.
I don't have the same issues with the radius, because I have always vaped to the experience, and not crippled by having to know the numbers, and I also feel everybody else should as well. Nobody is going to hand out citations for
vaping above or below a limit.
I could turn the whole display off and never turn it back on, and still have a great vape, so watts, volts, whatever. I wish they would do away with both and have it go from 1-10 with 10 being all the way up, and 1 being all the way down. I'd probably be
vaping at "3". But to me, it sure doesn't matter.
For my use... I would never let the display metrics get in the way of owning such a wonderful
device.
