I hope I have done the sums right, happy to be corrected.

1st 14 games
Home 7 games 17 points av 2.4pts
Away 7 games 12 points av 1.7
Overall average = 2pts per game

2nd 14 games
home 7 games 14 points av 2
away 7 games 8 points av 1.1
Overall average = 1.5pts per game

OVERALL
1.82 Average points per game
Home average 2.2pts
Away average 1.4pts

Games remaining...
home x 9 including - Mansfield, Wycombe, Coventry, Luton
away x 9 including Newport, AccyS

Points required for automatic based on recent years = minimum of 80?

Year 1st 2nd 3rd
2016-2017 87 87 85G
2015-2016 99 86 85
2015-2014 94 89 85
2014-2013 84 81 81
2013-2012 83 79 78
2011-2012 93 88 87

So we realisticly need around 30point..

Where will they come from?

20 home and 10 away?
