just what a few crawlers happened to grab" is close but not the whole story, lots of pages were excluded on purpose if the robots.txt blocked it or the site owner asked to be left out. Your bowling page might have just never gotten crawled at all.

We do this with everything without even noticing. Restaurant with 4.1 stars and a review saying "the owner comped our meal after we waited 45 minutes" beats a spot with 5.0 and nothing but "great food, great service" every time. People scan for the one review that shows how a place acts when things go wrong, because that is what they are really scared of. Perfect ratings read like ads, and our brains just skip right over them. The messy review with a real story proves someone actually picked up the phone at 11pm, and that is what a person with a burst pipe needs to know.
