I have no issues with locking. I use ArcticFox where you can set manually. I measure as soon as I build it, lock it. I do build over 0.6 ohms which gives me more tollerance but if my vape is too warm I manually increase locked value. If too hot, I decrease it. By now I can guess correct temp when I vape.
However, thats only temporary. In the morning when I wake up and coil was not used for long (also temperature of the room stabilized if summer). I measure again and fine tune.
This way all my coils wotk perfectly within 5 degrees tolerance.
I'm checking that out. I always thought that manual adjusting of the coil should've been a thing back to D2.
For me, the downside of TC is due to me...
Just like when I smoked, I don't hit as hard or inhale as deeply in the am. By evening, I hit the cig a little harder. Same now with vaping - I start at around 8.5W, and over the course of the day, it increases, usually only up to 9.- or 10W.
I really liked TC when I first started it with a DNA, so I just set up different profiles. But that gets kind of fiddly, to know which profile to change to, or change the settings within a profile. And every now and then, I just want a more powerful hit. Using watts allows the temp to increase with longer draws, so it allows for that.
But once I looked at all the data in eScribe, I realized I never approached "dangerous" temp levels anyway, so now I'm back to watts. Much easier just to bump up a half watt or so at a time. Truth is, though - I'm glad I did TC, because it now gives me a little piece of mind. But if you like a consistent vape, TC on a mod that does TC well is fantastic.
That's why I like TC. Sometimes I like it long and slow, sometimes I like it hard and fast. TC adjusts based on what the airflow across the coil is doing. If I want it rough I can bump the temperature. Feel like Tina Turner singing Rollin' on the River.
You certainly haven't sold me on the great god DNA. Different profiles for TC? Is that curves?
To me TC is the same, it's why I like it, no need for different profiles.
