What on earth...

So I'm confident with my S&N diagramming. But I'm just having a hard time grasping the fourth rule on why the game setup video had the diagram the way it did. I wrote it like this M>K -> M>H H>M -> K>M I noted that it was one of either the primary or the contrapositive and it couldn't overlap, with that, why was rule four written out as two arguments with two contrapositives in the video?

It's really just a matter of personal preference. I think the videos are done in a way that it puts ALL the info out there, to make sure that everyone can follow along. So, I think they try to over diagram. I think your diagram is simpler, easier to understand, but requires more thinking to translate the words on the page into it. I personally like yours a lot more, but both are valid.
