We managed to turn around an Accept / Weak accept / 2*borderline rejects into Accept / 2 * weak accept / borderline accept and get accepted.

Another paper was Accept / Weak accept / 2 * Reject and turned into Accept / 2 * weak accept / Reject and got rejected. Too bad there was really a reviewer with incessant despise/misunderstanding of the paper. But we will find better venues, no worries there.
