I'm going to give you some honest advice. Ignore the voltmeter! You're starting to find out why I think they are useless for anything but diagnosing a problem or satisfying curiosity. My VV doesn't even have a meter. Adjust the voltage and juice flow until you are getting a good vape. Don't even look at the voltmeter. I do find that on the Penelope, I vape it at a higher voltage than I would if I had the same resistance in a commercial atty, Yes, I do get curious and see where I get on a new device but, I don't use meters to tell me where I like it. So I happen to know that currently I'm running 4.9V on a 2.1 ohm coil. On a commercial atty at that resistance, I would expect to run around 4.1V.
Once you find the settings that give you a vape you like, then you might have a place to start but, with a hand wound coil, you aren't likely to find a single voltage that will always be the one. Also as things wear, you'll find it needs a little adjustment now and then. Don't let the meter dictate what you want.
