I found that to be true as I first worked with introducing strain process for winding super_X_drifter's original torch oxidized microcoil. Turns did impressively heat each other and particularly at the center point of the wind. As noted by many this was often too much at some dia-turn combinations to thoroughly char cotton in operation.
Not enough peep's liked this idea to satisfy my goal to rapidly expand contact use. So I abandoned torching as deleterious to alumina formation anyway and introduced the strain wound contact in the Spring of '14.
Once we wind with just enough strain to ensure practical turn-to-turn maximal proximity we will have evoked the beginnings of elongation, input enough rigidity in the wind to survive pulse oxidation and achieved apparently enough internal reordering to produce effective observable optimization of vaporization. As most anecdotally refer to it…it's cool, by a factor of at least 25% over open winds of similar mass and same power. This is an observable, reproducible and measurable phenomena I believe as per the various confirmations of success of simple and complex creation by others.
So I'd agree, conventionally wound contact and even close contact coils can get exceedingly hot producing quite the throat hit. Something which seems to have been very unfortunately equated with authenticity and satisfaction in this community as requiring high power and lots of diffusion in my opinion.
As to flavor, there must first be vaporization to taste anything. A more effective rate of vaporization expectantly yields more flavor.
So it's your conclusion Leti I'd qualify. A t.m.c. would produce less flavor than a comparable spaced if run at less or greater power. The first is obvious —less vapor, less flavor. And we can't taste what's not there. Spaced winds tend to be run at more watts as they run cooler due to the spacing. So generally we just up the power and say great vape. We get some additional flavor despite the randomly spread coals. But notice that we're adding power without a like kind increase in contact surface. So where does most of that additional energy go?
In the 2nd ex., one not properly oxidized, a non-oxidized or inconsistently oxidized closed coil will perform in an unpredictable fashion producing diffusive heat from some turns less with others but generally hotter, much. With more power loss, less flavor. Add diffusion and vapor is thinned, it's texture changed, reducing flavor for many.
This doesn't mean that the flavor from a spaced wind is necessarily bad. It's just more dilute. It must be. You can't cook with less coal. With open winds you lose the advantage of contiguous turn reinforcement. Turns heat each other creating a very efficient uniform vaporization zone within the element from which there is less thermal loss to ambient but concentrated within the element.
There other magical things happen.
Good luck.
