I don't think that's very useful tbh. Like... If a reader already has a novel in their reading list, it doesn't really matter what time you upload because the readers will end up reading the chapter anyways.
Upload time mostly matters for the sake of getting new readers... And in that case you should regularly upload in different times so as to be visible to readers that log-in to the site at different times... And well, said new readers won't really be visible in your data because your story isn't in their reading list yet.
So uhn... I dunno, this feels like a waste of Tony's time. I don't think the feature would have any real use.
