Generally, the only types of comments that are below −3 that I upvote are ones which I think add a perspective to the conversation which should be there but should have a different proponent. It’s rare that I find a comment at less than −3 which I would fully endorse (but I have my settings set to display all comments).
Indeed, my quality threshold to upvote comments at −1 is much lower than my quality threshold to upvote comments at 0.
What function describes your threshold as the negative values go below −1?
