Here are the highest and lowest possible positions that each National League club can occupy after this weekend’s fixtures. I’ve drawn lines under the automatic promotion and play-off spots, mid-table and the last spot above the relegation zone on both “axes” for ease of reference.

These graphics are explained here, but in a nutshell I crunch through every possible combination of results to work out how far it’s mathematically possible for each club to rise and fall.

Dag & Red can overtake Forest Green at the summit this weekend but can themselves be shoved down as far as fifth if results go against them.

It’s a big weekend for Tranmere and Eastleigh, who can finish it anywhere between 3rd and 12th. Any of the five sides beneath them could drop out of the top half at Sutton‘s expense, should they win at bottom side Southport.

The four-point gap between Torquay and York has cut the bottom six adrift for now, although plenty of movement remains possible on either side of the divide. Nobody is guaranteed to start next week in the relegation zone, although Southport would require a huge home win to overcome their poor goal difference.
