This isn't an answer to your direct question, but it seems to me as if
you've already decided on a solution (figuring out an offset) that's
non-optimal. If you're using offsets at all, you must have a distinct
sort ordering; if you have that, you should be able to accomplish the
same thing with a where clause instead of an offset. Is there a
particular reason why this doesn't work for you?
Perhaps the better question is "what are you trying to do with this?"
There may be a higher level solution that can be given.
