Right, I guess the question is, are you sure that my overall chances of being upgraded are better by waiting for P->R to occur, rather than just having an early check in time and hoping that is the tiebreaker for a battlefield?
On a related note, does the auto-companion upgrade for Plat companions on a single PNR work for battlefields?
