What I'm saying is that the number itself is pretty meaningless, you're telling your mod to cut off at the point that you are setting (using that number), but that cut-off is a TRC value according to the coil that you placed in your tank.Well, the one dna mod I have, if I set it to 420 degrees, it GOES there (or it seems like it) after one slow priming puff. It's certainly possible I didn't set it up correctly, but I have had that experience if I leave my temperatures too high. So, IDK. It's probably me, not my mod, but setting it up in the right TC and using that ceiling didn't work, at least on that mod. I should probably try it in another mod to see if it's across the board and etc.

If you were to put another deck with a totally different build, what your settings are for one build, will not work for another build, simply because the parameters have changed.
The number is simply an easier way to do the settings as people understand degrees, but if you'd be doing the settings by the amount of curvature for the TRC value (which is what you actually are doing), most people would scratch their heads and be completely confused.
