It's a good research tool, but it doesn't do such a great job of picking enough winning numbers. It has seven reports that send their picks to the score board which in turn sends it's top numbers to the smart picks. You have to hand select the weights for each report and how many numbers to work with so there are many possible suggestions to wheel or you can just leave it at the default settings.
The problem is none of the reports pick all the winning numbers. When they are combined even if all the winning numbers were picked, they may only appear on one chart so they don't rise high enough to be picked for wheeling. If you ask smart picks for all the numbers for the previous draw and circle the numbers you soon find one or two in the top ten, some in the middle and zero one or two toward the end or among the least smart picks. About the only thing you can do is map the smart picks for where the winning numbers fall among them and wheel those clusters. As wheeling is more expensive the more numbers you play a three number prize is the best one can play for guaranteed over 18 numbers in the hopes the wheel will win above its guarantee. As so many lotteries have cheapened the four number prizes, often a win won't even pay for the wheel.
