Agreed - and I think this evidence seals it.
Prior to February of this year, all YBM-ups cleared to PN, and because of this the web interface will still prompt you that one is available as long as there is PN space. But all elites below 1K clear to R(N), so in this case where there is PN but not RN space you cannot clear the instant upgrade. You can call back in R/RN opens up.
