Firt rule of VIPFER: you can only break even.
I've flown a bunch of VIPs, up to and including -2 for CNO. we always interpreted the rule as a URL FO/GO could take over and boards often included questions about flag doctors, surgeon generals, etc but the right answer was unless the FO/GO was URL they got 49% of the vote.
That said, ensuring the code isn't up ICS is a solid move. Some will request it ahead of time in which case there's not much you can do but re-read how the PVT switches work.
