Ok, took a recovery break, that was anything but recovery, another story!
Anyway,
@Uncle as the others said, you are way over complicating TC! It took me a little while to sort it out in my head as well. At first I thought you just left watts maxed and set your temp, unless you like a really hot vape, don't do that!
Think of the wattage you vape at as how fast you reach the temp. At 10 watts it's going to take a while to reach temperature, at 50w it will reach it faster, at 200w it's going to be almost instant. Like the others said, 20-30w (I use 30w on everything now) is a nice "ramp up" wattage. This doesn't heat the coil too fast and allows you some vape time before hitting protection. A lot of people see the mod hit "temp protection" and think it's an error. In fact this is the mod doing its job, the coil has reached the set temperature and is now cutting power until it cools, then heats it up again.
It's actually kind of funny, way back when people would complain about the "rattle snake" noise some of the cheaper mods would make because of the cycling of the PWM in their circuits. Now days we expect it with TC!
But to make this as simple as possible, set your wattage at 30, set your temp at 400deg F and try it, you want it warmer, turn it up, cooler, turn it down. If it heats up too fast turn the wattage down, not fast enough, turn the wattage up.
I'm sorry it's not as easy as take the resistance and add 2 to get the voltage for 11watts, like we did back in the day.
I hope this helps some, but it's not as scary as it seems.
. . . NOT NICE . . . Just Sayin' . . .
