Technically speaking, TC is still really only just a marketing term. It doesn't actually measure the temperature in any way, as the resistance that is measured by a TC mod does not reflect the real surface temperature of the coils with great accuracy. It offers only an approximation that is relatively crude enough to invalidate the suggestion that it can do a better job at controlling the temperature than what I am able to achieve by sensing the vapor with one of my mech setups. For one, local heat buildups occuring in various different parts of the coils go virtually undetected with a TC mod, as the mod can't measure differences in resistance between one particular portion of the metal and another nearby portion. In fluid dynamics, there exists such a thing as adsorption effect. With an advanced coil build that uses the type of outer wrap wire that is fairly thin, typically, there will be numerous tiny cavities and crevasses that are interlinked through which the juice can keep flowing vigorously, at a comparatively much faster rate, out of the cotton wicks and onto the metal surface in every location, more homogenously in such a particular way that local heat buildups will be adequately suppressed as a direct result from this.
Remember that the part of the juice that is moving fast out of the cotton provides a significant cooling effect the strength of which is largely determined by the flow rate that characterizes this same part of the juice. With strong airflow smashing right into the coils, it will also be obvious the fact that the hot wet surface receives powerful cooling effect. In addition, faster evaporation provides stronger cooling effect, as that's how a freezer factually works... it uses evaporation of a liquid in order to create that effect. Furthermore, increased stable airflow across a liquid surface also accelerates evaporation thereby causing stronger cooling effect to be strengthened even further still. Also remember that juice fizzes briskly if using "angry" coil builds at high power such that the specific part of heat transfer that occurs inside the fizzing portion of the juice is lightning fast thus the combined effect of all these factors I described is that localized heat buildups are kept truly negligible. By contrast, TC mods are incapable to get a handle on changes in resistace that occur in the outer wrap wire that surrounds the core wires. This is due to the simple fact that very little current is flowing through it, compared to how much current is flowing through the core wires. Adjusting the TCR number to try to compensate for this, doesn't address the root cause of the problem.
Finally, yes of course I can get a dry hit from my mech mod if I forget to drip on time. But that is
precisely why I never forget, just like I also never forget to keep my balance while riding a bicycle with no training wheels. And I don't need to know speed measurements nor require some sort of cruise control to still be able to control my bicycle's speed accurately enough that I never unfollow the optimum trajectory. That's just me, though... so my vaping style is fundamentally different, yet, the main relevant principle of keeping the coil temperature always perfectly under control is nonetheless applicable to it, and, that is still regardless of all the semantics of who uses what marketing terminology or consorted blatherings for describing that principle. There's pros and cons to everything. Including mech mods of course. And including TC mods also─
AND training wheels on a bicycle.
