To be honest it is never going to be possible to prove any of this stuff.

Everyone is in a crappy position.

You could have booted CAS 5 from Bios, switched to CAS 4 on 680i (which would do nothing) and booted 965p direct. There is just going to be too many variables. The only way you are going to prove beyond a "shadow of a doubt" is by having everyone DV cam any WR run.
