I'll take your last post first, Ken, although you may not have meant what I read. I have been in many DACT fights with F-16s and they can sustain 9 g for a long time, as my students and my neck can attest.
Now, not sure if you were using "corner velocity", sustained rate, sustained min radius, or g. Again, we don't have the SEP graphs or rate/radius/g graphs available so it's going to be a tricky one to call. Max energy manoeuvre is probably a better tactical measure, ie where the g limit, altitude and SEP all meet. But only if folks are firing real weapons.
