That's code size, not optimization.
I was meaning the yellow 4, the code size is correct 68, but the yellow four is my worst codes ranking, on other filter sets, where the numbers are in the hundereds, the header line yellow number is the ranking of my worst entry, while the code length values is my best..
There are per-language leaderboards
You get 200 points for being first in a language.
Your best 5 langauges count in the puzzle ranking, so you can get 1000 points at most.
It looks like others solved it in more languages. That alone can make you 2nd.
This explains the bigger picture ranking. Although it seems pointless (to me) to rank a code golf on how many languages you submit in.. but now I know what to game it "win" the ranking I will play that game...
