It may be worth noting that the way to get to “upvote every non-terrible post at least somewhat” while still leaving space to “upvote decent posts a lot” is … to have at least some of your users be much more miserly with their upvotes. Even if your goal is to have most things end up on +1 or so, you should be glad that there are users like Lumifer (and, for what it’s worth, me) who mostly only upvote things they think are unusually good. (If everyone upvotes almost everything, you have no way to distinguish better-than-average posts or comments from average ones.)
Yes, there is a point at which more upvoting starts to saturate the set of possible scores for a comment, but we are nowhere near that point IMO. And if we were, I think it would be much better to add a limited-supply super-upvote to the system.
