No worries.
The idea behind pulsing (for me) was to measure the temp with my tongue, if I felt it getting warm I'd back off for a second, whilst still inhaling, then back on for a second or something, playing it by ear
A TC mod will back off on the power (instead of stopping) automatically for you, it's a seamless experience where the temperature just stays at the right level for good vapour. If you need 20w it'll give you 20w, if things get a bit warm it'll back off to 4w until things cool down.... and so on.
I went for stainless steel wire in the end, bit less accurate but more robust and safer if you accidentally put yourself in wattage mode.
