My 2 cents: the (somewhat) famous saying goes: All models are wrong, but some are useful. Notice it says some are useful, not all. In the case of this analysis its topic is radar reflectivity which is heavily affected by the geometry and detail treatment of the object. If the model used in the analysis itself has multiple macroscopic differences (shape of canopy, strake design, etc) to the real-life object that’s distinguishable using the naked eye then there’s just too high a possibility that these inaccuracies will bring enough “noise” into the system that the results get effectively meaningless. This may be the case, this may not be, we just don’t know.

And since we don’t know how inaccurate this analysis is, it’d be irresponsible and borderline stupid imo to treat its result as an even partly reliable source, just because “there’s no better alternative”. Not to discredit the author’s efforts or anything, just that no good information on a subject doesn’t mean anything is necessarily an improvement.

It's getting personal because the last five page of a flagship thread (if not the flagship thread) are being wasted on this meaningless back and forth. The model is useless and further discussion of it is also useless. Enough already.


Exactly, and this post - with which I can only agree - ends this discussion. All arguments are on the table, and anyone can decide on if this model is exact enough to result in an accurate RCS-analysis or not; IMO clearly NOT.

Just post this video here for reference, not sure if what Fu Qian Shao said is correct or not. He said PLAAF has over 150 J20 as of now.

To address the numbers, there are probably slightly over 200 J-20s in service.

Second, and most importantly, he is not particularly reliable and is not worth listening to.

2. We already know about this (higher than expected production rate)
I wonder what kind of connection this gal has. She has written things proven to be both wrong and right. Yet, despite later-proven inaccuracies, she still remained the main PLA reporter for SCMP. I wonder what kind of family or other connections she has to keep reporting on the PLA. She could have ruined SCMP's reputation long ago. Yet, she is still here using her "internal sources."
