Yes it's mandatory to read the coils cold.
I observed the hot spot situation from another perspective and instead of wondering why the airflow didn't help much, I was playing around with the coil.
In the manual you can see the original form of the mesh coil. Do you remember my hotspots? No wonder, I don't like the pre-built layout.
Here is my first try with NiChrome wire for a proof of concept. Inspired by tinymight.
The coil reads 0.78 ohm and was very sluggish in heating.
So I modded another mesh screen to get the biggest and most even heating area as possible.
I will try this new coil style the next few days, also with my beloved capsules, even with lid on it.
Meanwhile I'm very pissed about the loose air control of my stealth topcap. I need a better O-ring ASAP.
Also the drip tip is a real disappointment. I cleaned it with an iso cotton wipe and when it was dry the glass part was loose because it is glued on the metal part of the drip tip. I had to bend the metal a little bit so now the glass is held by pressure.
I ordered a stainless steel 810 drip tip. It also has a mesh.
This should have been shipped instead of this glued glass thing.
Nevertheless I like my herbie but it's really challenging to reach the personal sweet spot of performance.

Edit after some tests:
This new mesh layout rocks hard.
By far my best result since I got herbie.
I used a capsule - with - lid. Gorilla Glue.
Startet at 50W and finished at 62W.
Half opened airflow, moderat draw speed.
Stealth top cap airflow almost closed fully.
Now we're talking seriously!
Nevertheless, I hate the loose top cap airflow ring. It sucks hard when you are outside in the evening and while you're switching capsules, your loose airflow ring fells down to the ground, rolling away, so you have to search it for several minutes until you find it near a gully cover.
@Vape Engineering Is this covered by warranty? ;-)
