Thanks for the replies.

The saddle appears to be level, but I'll check it with a level and make sure. It's an old Cinnelli unicantor and the seat clamp has actual bolts (not allen heads) under the saddle. I realized last night I need to get a mini socket set to try and change the seat itself as I can't get those old bolts to move with any of the tools I have on hand. Don't want to strip them and it seems likely they haven't been moved in decades.

But I'll definitely go back up a bit on the height.
