I know that A drawing B and B drawing C doesn't mean A vs C automatically end in a draw too. But it means they are at least somewhat close in terms of battle strength.

And I don't think that in a post timeskip battle Meredy would automatically win. Since we have no idea how much Meredy improved, there is plenty of room for the authors to make up whatever they want to happen.

It wouldn't be much of a stretch to argue that Ultear and Jellal held Meredy out of the battles as much as possible.
