It is impossible to know, it seems to me, since the "rule of four" is, as it were, an internal rule that the Supreme Court has adopted for itself. If a decision were ever made to grant cert in a case in which fewer than four Justices had desired to hear it, there's no formal mechanism by which we'd ever find out about it.

Reminds me of a soundless eternal forest where no tree ever falls for lack of someone to hear it.

If even one strongly wants it to be heard there is often further consideration. That would lend additional strength to the contention that such an interest is more likely in the only case to go to SCOTUS so far in which standing is not the issue but the questions presented go to the merits.
