I often find the upvote to downvote ratio to be a higher sign of quality than purely the number of upvotes. If they showed me the ratio, I still might get the same value from it.

While I agree there isn’t much signal in 1:1 and 4:1, it’s been my experience that if a video gets a downvote that quickly, it probably isn’t as good as a video only attracting upvotes for educational, howto or technical content.
