ArXiv feeds are organized by category (more like tags in that papers could be cross-listed, but need a primary category). Daily traffic in different categories is very different. Eg, at some point I used to subscribe to hep-ph/hep-th/gr-qc and they combined to something between 50-100 papers a day. I’d mostly just scan the titles/abstracts, to pull out particularly interesting papers.
