There has been some discussion about the GAP theory over on the Lottery Systems forum http://www.lotterypost.com/thread/157912.htm.
I am interested in working with and tracking New York's numbers. For anyone who is interested in having a look at the GAP theory check out the thread. If you are interested in seeing what is going on with the New York P3 numbers from 5/1/07 to 7/28/07, see the charts below (you can highlight future numbers as they fall. The charts are for combined Midday and Evening P3 draws.
