So we're currently sat in 7th which looks like it's the last playoff spot. There's a dotted line underneath 1st place, a dotted line under 2nd-3rd places then another from 4th-7th. Is this something new for this season or is it because of Bury? How may teams go up? What are the rules? Obviously dotted line under 1st is automatic.

Also, something that's always confused me about the national league. If 4 teams go down and 2 come up from the National League North and 2 from National League South....what happens if all 4 relegated teams are in the North of England?
