Just noticed that Colchester have rearranged their home match v Doncaster for 23rd April, so that means Colchester will have 9 points still to play for when they arrive at Meadow Lane three days earlier whilst Notts will have 6 to play for.
If FGR or Sutton do enough to put them in the bottom two and we aren't at least 10 pts clear of them on the morning of 20th April, we won't be mathematically safe going into the penultimate Saturday match.
We should be at least 10 pts clear of them by then (the gap is currently 15pts) but not impossible that we won't be if Maynard's recent form continues as is.
