Given that annoying downtime yesterday, and the IP changing for the forum, we missed our postings.
So, just for the sake of it, the 15 numbers I had selected for this draw were
4-8-10-11-15-17-22-23-29-30-31-32-34-43-46
I had 2 but changed it for 11 instead. I saw 34 as a strong repeater, and paired the others. 17-22 were one such pair.
With this set I got 4+B out of 15...
but only one 4 match plus free tickets.
My strategy here was looking at the last 13 draws and comparing them to their skip/hit probabilities.
