Mate, don't want to piss on your fire but you know, and I think the responses show that people have correctly concluded, that there is clearly more to this situation than simply one aspect of one trip. Forget the MSA thing. There is nothing you can argue that will vindicate you with regard to that. '2port' hit the nail on the head when he said:
"MSA's only have 1000' clearance... Possibly the SALT should be 1000' higher than the figure you briefed.
AND
what is the teaching at the school? If they teach use the highest MSA regardless of the arrival sector, then that's what you should do."
Don't get me wrong, I'm writing this as a mate who wants to see you succeed in your flying carrer. I'm just attempting some damage limitation to your case which isn't helped by the threads you've posted. Concentrate on moving forwards and convincing the relevant people that you should be considered for another type. I wish you all the best with any appeal but I'm not sure that this is the best place to voice your personal feelings about the situation - you never know who's reading!!!
Good luck dude!
