185, sorry but your data is too disorganized to follow. Perhaps you could organize it with labels for what the key quantities are and post it online with a link here.

As for the argument there may be upward tail load I would not dispute the possibility of that. But if you are arguing tail stall may occur then you have not shown that to be the case. To do so I think you would need to show the tail was beyond its critical angle of attack. Flight data is what really tells the story and hand calcs do not. I don't think you have that data, and it is not public.

As for the theoretical question can an aircraft be statically stable and have a CG behind the center of lift on the main wing, it can. The tail would have to be uploaded to compensate and as long as the overall center of lift for the two put together is behind the CG it is statically stable. If the CG is so far back the center of lift is equal to the CG location then it is neutrally stable. Unstable and neutrally stable CG locations are not approved for Part 23 aircraft.

There is a nice link that explains this idea here .
