0.2 ohm notch? Up the wattage. Start at 20, work your way up a few watts at a time, especially as it's a new coil and wick. You'll probably end up around 40W.
As to temp control, there is no actual thermometer. Rather, the chip monitors the resistance of the coil, which changes as it gets hot. By knowing the behavior of the metal used, it can extrapolate from that the temperature the coil is allowed to max out at. That's why choosing the right metal is important. The Ni profile won't work well with a SS coil. It gets way fancier than that, with custom curves and TCRs, but no need to go there now, and no custom curves on the Pico anyway.
Got your last post. If 15W and 145 C are working for you, enjoy it. Big difference from your Lavatube.
And yes it is a 0.2 ohm. I tested with the multimeter before I put it in and it read a bit higher but somehow it seemed to drop a lot after I burnt the heck out of the coil. Baking it to Lava red probably dropped the ohm a bit.
