The checker doesn't display anything useful, but I do see something useful if I click on debug output. Couldn't that info plus a summary line like "you've found 5 caches sizes from only 24 CO's (25 needed). " be displayed in the checker results section?

I will not fix it because it violates 2.12.10 Source of critera

Not acceptable
