I had a close look at the drawing yesterday, the port being situated in a recess bugs me. You really want to test it as you say, but tested using what? Just by looking and sniffing at it?
Also, the results of your friend's heater is by looking etc only, the real truth will come out using a gas analizer. And besides that, what other heaters do you know of to compare the one of your friend's with? My point: you aren't in the position to really test it, just by running it and calling it perfect, 99% of novice stove builders are doing exactly that.
The little nooks and crannies in your design will prove to be the "devil in the details", in my opinion. There's a 45 degree angle in there too, creating a very sharp edge which will break off easily. The riser seems to be done in one piece, that's a problematic thing to do as well.
Just my five cents.
The fact is that I am a "novice stove builder", and a combustion analyser is absolutely not in my budget. But I know you're right, looking and sniffing is just an approximation. Whatever, I need to build it if I want, a day , to run a testo analyse that can be provided by a professional stove-builder.
I understand that my changes are annoying you, as you spend lots to make a very powerfull stove. I have an immense respect for your job. To my opinion, this is like a F1 engine, and my goal is mostly to build a simple car, so I'm not perturbed by loosing a bit of efficiency as long as it is only few percent.
To compare, there are 4 batch-box that I've build respecting your specifications, and compare to classic stoves it's far better, even the less efficient of my builds.

I've supressed the 45° angle. For the riser, I just draw it simply to figure the place it take as there are different way to make it and I've not decided wich one i will use. If I cast it, it will be the same way as yours.
Thanks for your advices, and sorry for being stubborn.
