The Mishna was separated into chapters by R Yehuda HaNasi.
I see that at times there is a chapter break in the middle of a topic (today's example: Menachot chapter 1 & 2 - more examples here). It doesn't really "make sense" according to how we would likely break chapters ourselves.
Is there an underlying logic to why chapters were cut this way by R Yehuda HaNasi? Are there rules written somewhere or that someone extracted? I didn't find them in the Rambam's introduction to the Mishna.
