Going to have to owe you and the thread an answer 'till perhaps tomorrow night. Sched tight here. But check your PM's.
Yes, on the diminished flow due to geometry (and airflow, as to no avail if the juice isn't there to vaporize) and just getting cooler at the end. In function t.m.c.'s do continue to get hotter as all coils with longer pulls. So you'd expect more production and more air required. If cooler in your case the airflow is more than adequate to overcome even the dry state of the coil at the end of the draw. Strain winds actually require more air than conventionals if running properly. End turns must also be right on spec exiting at 180deg opposed and not pulled away. In a proper t.m.c. they'll actually run a tad cooler then the normalized remainder. If not contiguous, you may get a hot leg.
Good ex. following of the color diff above. Note the displaced 2nd turn from right running very slightly cooler as incongruous with the rest. The product of overly exuberant tweezer compression when warm.
Such seemingly minor differences may result in perturbations of internal fluid and air flow, imbalances of pressure limiting the output of the wind. Also the accretion litter from that end of the coil. Symmetry of these winds is the goal and important. We'll get back to your 1st on the next go round. Notice the symmetry of vapor egress again here (breaking in at about 30W btw)...
Another example of a successful target (vert's for the 454)…
K23x2 7/7 2.80mmØ=0.2616Ω 52.33-67.43W (14.14-16.06A) 156-184 mW/mm²
Surprisingly cool and quite dense clouds at near 70W (4.2v) mech. Even more of the same when driven hard on a variable at 45W+.
Back soon.
Good luck.
