This issue has raised my eyebrows. Are we sure that it's an ohms to v relationship or possibly the coil or setup? I'm assuming it wasn't just one setup used. All premade coils?
Is it just temperature hit or possibly a hot spot? All on silica? Something just sounds off.
Yeah I am using Leo's coils, they just act a bit different in this thing, and I don't know why, I have 2 of the same coils, in loki labs tanks. The BB's voltage settings are from,4 volts to 5.5 volts, on my provari's I have my volts set to 3.2 to 3.4 volts, and always tastes great. My BB I have it set to the lowest setting that it will go, 4 volts. The guy that makes them says it works best with a 3 ohm coil, at 4.75 to 5 volts, but it gets real nasty if I turn it up that much.
