I decided to test it and bought the cheapest on the market, NeuroXL.
I know it's controversial to use and it has been slammed before, but I decided to try it after reading LottoPirate's hit statistic. LottoPirate, which I believe use a programming library from Ward Systems for its predictions, is able to predict one line with 3(or better) out of 6 numbers correct in 1 out of 4 draws in a 6/49 lottery.
Perhaps it sucks ass, but it will be an interesting test. If it sucks, I will try to use it on horse racing and soccer betting instead.
This thing freezes up Excel for hours. You can't do anything else on other spreadsheets in the meantime. Now I know better why it's necessary with a workstation or a personal supercomputer in addition to your usual PC. What if you got only one PC and it crashes in the meantime? You need to start all over again. In addition having a powerful PC with only necessary software and utilities installed will prevent it from crashing all the time and get the job done fast. Now I got an excuse for buying one. Better start saving (or win!)...
