Ok
Looking at the table, if we win on Saturday and any two from Weymouth, Halifax, Northwich and Farsley drop points (lose or draw) then safety will be in our hands.
Put another way, a win on Saturday will mean that three of those four teams will also have to win then AND win their Tuesday games, otherwise we will go into our last game of the season knowing a win will keep us safe.
If by some miracle they all win both games, then we would go into the Weymouth game needing two from Halifax, Northwich and Farsley to drop points.
Given that it's highly unlikely that two of those teams won't lose or draw one of their last three fixtures - I'd say that survival is no longer in the lap of the gods and is now firmly in our hands
Simple, no?
