Yes the organisers choose 5 matches for the day and post them for you to predict. If you ban a choice you get double points. Each prediction is worth a maximum of three points, If you get the number of sets and winner right you get 6 points, if you get the winner right but the sets wrong you get two points with a ban and if you get the winner wrong and sets wrong or the sets right on its own you get zero points.
Thanks for the explanation
I will join in next tourney, do you have to post predictions before a set time?
