Jeff,
You are certainly not reaching, there is a potential here. I would interesting to see what would happen when you are tracking the following 3 Numbers
123 (Front)
124 (First two and Last one)
134(First and Last two)
and 234 (End Numbers)
Tha might take a bit longer but might give more interesting results, but when you keep in mind that CRUNCH in the current version ins Boxed/Straight oriented this might give you better results to combine the results. Just a thought though.
Once the new updated CRUNCH is available which will still take a while I am certainly trying to make a CRUNCH 4 available, the problem there during test is the speed for the Javascript based program to get though all 10,000 options. There are many requests from the Group members and people like the systems that should allow me to get the time and money to make CURNCH 4 possible.
Good Luck and keep us posted with results.
