I assume that's a half POT? I'm gonna say that she should try to get this fixed at Runner Relations, but also that it's possible that she gets bumped to D instead of C. Here's why:
That POT would put her in C for the half, obviously they're looking for 2:15-2:30 for that race. HOWEVER, it translates to a POT above 5:00 for the full.
@DopeyBadger had a calculation on this yesterday. That obviously puts you in a dicey situation for Dopey/Goofy: the POT is good enough for one race, not good enough for the other. RD has said that if you put a POT in that doesn't actually qualify for the POT corral, they'll put you in the last corral. But they don't provide the chart you mentioned, it's technically an educated guess from the rest of us as to how they handle this. So I think it's unfair to penalize her for a POT that works for one race but not the other when we technically don't have all the information. I'd ask about this but also be prepared to say you didn't know how the conversion would work. Based on what you're saying I think she should be in D though.
The POT was in the range of acceptable dates for this weekend, right? That's the only other reason I can think for them not accepting it.
