Well done this weekend Johnny! You are heading for the right way.
I tryed your system this weekend, but decided to make one change. Went for trebles instead. Made a small profit after hitting 4 of 5 in the first group and 2 of 5 in the other.
Have you tryed with trebles? I know the total unit is higher and more coupons in play, but i think it worked pretty well, at least this weekend. Might have to try a few weeks more, before its easier to make a conclusion. I will give it a try
Good luck with the system in the next weeks!!
