One strange phenomenon I've noticed (while trying to teach myself perfect pitch) is that, when trying to reproduce (say) middle C, if I'm off, I'm only ever off by multiples of a half-step. That is to say, I'm singing exactly a B or C# (or on a bad day, Bb or D). My ear is sharp enough to detect if I were, say, a quarter step off.
This ability seems to fall somewhere in between relative and absolute pitch, and I'm sure I'm not the only one it is true for.
