28 points from 7 home and 7 away games DOES keep us on target for a 92 point win-at-home-draw-away finish.
7 home @ 3 points + 7 away @ 1 point = 28 points, which is what we have now.
Maybe the OP is right.
We have made up the dropped points anyway for a win-at-home-draw-away 92 point finish, so perhaps it's better not to now be trying to protect a must-not-lose record.
