I have done very little research into this
Last week i tipped all the winners if you exclude the drawn game, 4/7 i believe won by UNDER 39 points.
I will admit this is just a 'hunch' type thing and drew inspiration from analysing this weeks games and anticipating some very close contests. I believe if you can tip 5-6 winners this week, you will be in line to make profit.
This is the type of thing that can be extremely profitable 1 week, and a disaster the next. Lets see how im sitting after round 22
