I have only played around with a view possible results and added goal minutes based on these scenarios. For example if I know change the 2nd green line, the goal minutes to 15, 22 and leave 10,20 for the second game the score would be that Team 2 goes 1:0 up, then Team 1 equalises (gets deficit back yes) and team 2 loses goal advantage but the formula says Team 1 (4 When Goal Down Gets Deficit Back No) and Team 2 (2 When Goal Up Gives Lead Back No.) Even though Team 2 lost the lead twice and Team 1 recovered twice. Does that help?

Again thanks for your help, really appreciated.
