Back to spaced coils and heat. I have experienced a hotter than expected vape from spaced winds but it always came down to under wicking. Wick them heavier and soring heat probs seem to go away. That said, I have always found contact coils to be hotter than spaced but have always attributed it to higher efficiency because of proximity of turns. So I have always been able to run at lower wattage with contact winds and still produce equivalent heat to spaced winds at slightly higher wattage. Could it be that I have never successfully wound a true tmc?
It would seem that Kanger agrees with you. As they're royally packin' their hula-hoops. And don't get me wrong. I'm not panning spaced winds in my post above. There are juices I've liked in that config. If they're made rationally so they don't short or heat air, we're golden. I kinda see them though as kinda like puttin' the big pan on the small burner on the stove. You've got all that extra wick and vaporization potential sittin' idle (geometric volume potential for the device).
The wire can't carry any more energy whether the wind is opened or closed. If we're able to knock down the wattage as I've successfully done here with this most recent build it's due to the the wind
more effectively conducting energy to the wick (less dispersion) as
State-of-Flux aptly explained with the
spread candle analogy on his blog.

Brother, you have no idea how many times I've asked myself that question. When is "sticky", (S)ticky?
The phenomenon that super_X_drifter described and I watched from afar trying to decide whther to quit, invest or dismiss was
stability of the micro occurred. When he got to proximate contact with compression it
stopped being overly hot which was happening with close contact. Not only was the input energy enough to sustain shape but to nominally retain turn-to-turn contact. Then vapor production exploded. Well you might say this is impossible. It's the same current? Same wire mass? Same resistance? We know all of these are the same and if different, only ever so slightly. I thought so.
What I described as the rubber test is vape temperature. If you experience the radical drop of vape temperature accompanying that increase in production, you're there. No further Watts needed. A faster more complete phase transition of the flow has occurred. That is the
observable explanation.
Before I achieved my first micro, I reasoned as you did above. Wire's hotter, so there must be more vapor output. I now disagree. When wire gets too hot for the flow, vapor is dispersed. You heat air. You experience post-vaporiztion diffusion. Not necessarily more vapor. And often it sours (or mutes) the flavor as with an overheated segment.
Now wait a minute, you're gonna say, micro's
are hotter (concentration). Yep, but they work. And I'm sure you've built more than a few that have exhibited the above thermal characteristics.
In the absence of the t.mc. the main criteria we've been concerned with is resistance. But there is more involved in the vaporization process than resistance or simply line energy. I've tried to encourage folks to consider it more like cooking because we have a lot of similarities there in the physics. And its the new vapor we must want to see get right quickly.
Bro, I'm happy to acknowledge I'm not the best cook at the stove here. I prob miss hitting sticky more often than you'd think. But it's not from lack of knowing where it lives. I strongly recommend new users learn to wind by hand because it is ridiculously easy to find that strain level necessary for a given wire. And once you find it it's Memorex. We have an astoundingly efficient hard drive. However, for some of us recovering and executing those motor memories is sometimes difficult. Also, when you make a lot of them you can overdo it. Often that results in making a bunch of very tight winds which'll light up end-to-end, post to post. And you would be right,
that is not
sticky.
We're looking at a rather narrow shallow curve where wick/wire/power are matched to a rapid escalation in interior pressure of the coil/wick. That's where
the effect resides. As open winds are made symmetrical they can take advantage of tighter more directional wicking. And in such wick density proves to be an improvement in production.
When I see these massive cloud comp exhibitions on video and the magnitude of vapor crashing to the deck whatdayathink just happened?
I think we both know.
