Damn, I certainly can’t imagine voting 240x in a single day. There might remotely be that number of opportunities in my subscribed stream, but that would be like me forming an opinion upon every-goldurn thing that I possibly saw in that day. And beyond, really?
There are 303 comments in this post alone. If I have an opinion on 2/3s of them, I'm almost at the cap.
~300 comment posts are not the norm on the Fediverse, but I see a fair number of ~80 comment posts. If I run across two or three of them, suddenly I would have very few other opportunities to upvote.
Considering, on top of that, I post quite a bit and get a fair number of comments on each (I had ~90 comment replies to my posts on a pretty normal day's output on HistoryMemes alone), it doesn't take much browsing to hit 240 votes.
