The question is not about the accuracy of the Simulation, but the "estimate" RCS difference between F-22/f-35 vs J-20 because that RCS difference will be the biggest deciding factor in a BVR fight
Is there no reasonable guesses we can make about the RCS difference between these two planes? I know there have been various Radar simulations being published which only look at the shaping of these planes.
Everything that you need to know about that video and your current line of questioning is in my last reply.
Ignore, ignore, ignore, stop stop stop.
Just don't even think about that video and the question it raises. As I wrote in my last reply, no we don't know what J-20's RCS is and we don't know what F-22's RCS is. Public estimates are essentially useless.
So just don't even think that this is a question we can even ask or an answer that we can ever get -- think of it as something unattainable, and anyone who claims to know the answer in a relative way with number is full of rubbish and needs to be ignored.
Again, let me repeat -- DCS is just a video game. As a rule of thumb, do not think about extrapolating anything about real world performance or capabilities (relative or otherwise) from it.
In fact, I would say it is beneficial to pretend that DCS just doesn't even exist. Don't look at any DCS video on youtube, and don't ever play DCS, and don't even talk about DCS.
The net effect of improving military understanding will be better that way.
