Looks like no-one knows.
My best guess is that it wont make much difference, a fighter in fight turns more than a carousel so the only useful RCS is the average RCS,
unlike that of a striker that only deal with fixed known stationary radars on ground,
which among other things allow and encourage a steady course

The issue will just be with the models they use. Most likely there'll be a flat "plug" inside the inlets and nozzles of their 3d models.
There's no reason for their front aspect to have higher rcs than from a few degrees left I right of centre. The largest leading edges have the highest sweep angle away from incident beams from the front aspect.
You're right about the aircraft knowing it best and worst aspects though. There a video showing an f-35 cockpit somewhere and it clearly shows where each threat radar is and how close the f-35 can get to it while avoiding detection .... pretty amazing and unfair.
Rest assured most upcoming aircraft labelled as "stealth" have a low rcs front sector.

The topic at hand is the RCS model Kopp uses. It is incomplete, of course, and others have criticized it, but it shows a very interesting phenomenon with regards to the J-20. The J-20 apparently has very poor frontal stealth, roughly speaking, it has a frontal zone, due to canards, of roughly 0 dBsm. However, surrounding this zone is a high stealth region where it has a RCS of -30 to -40 dBsm, giving it adequate stealth provided that it is not headed directly at the target.
The net effect is that if the J-20 detects your emitter, it can change its heading to avoid being tracked, but it has the risk of being detected and tracked by an emitter before it can shake radar lock.
With this kind of configuration, what would be the consequences for air combat in BVR? WVR?
