Yes, I have a pretty good feel of the program in Pick 3. I have the full "paid" version of the program.
The setting varies however I have quite a good batting average when I go back to the last draw before the current day and mark the place it appeared from 1 to 7th place.
The program would give you hot picks based on the whole draw database and it is up to you to set the "Drawing cutoffs" and "Hot number cutoffs" to match the last results.
I have not perfected it yet but I'm getting there.
Just the same, end result for me is that the software paid for itself in under a month playing Pick 3. Can't say the same for Lotto 6/49 and Super 7 however the value of the draws databases/history and the wheeling features is almost equivalent to the purchase price.
All in all, I'm very happy with it.
