It was worth the try but I see a potential flaw with this system.
Since the algorithm is constant, ex. you -/+ X95, -/+ X48, etc, each combination will yield the same set of numbers.
For example, 3-7-7 will always yield the following numbers indicated below.
362,315,007,547,337,387,227,757,340,394,977,477,373,378,382,339,647,107,317,367,427,997,304,350,777,277,371,and finally... 376.
If I used 3-7-7 as my primary numbers from the 1/1/2011 drawing, it would have given me around 3 consecutive box hits for 1/2/2011,1/3/2011, and 1/4/2011. This is great but it is only coincidence.
So lets say that 3-7-7 turned up again at 1/13/2011 and you decide to use it again as your primary number. By using 3-7-7 again, you are going to be using the same set of numbers that is associated with 3-7-7. If you did use the 3-7-7 from 1/13/2011, then you would have gotten 1 box hit a few days later and no more. There will be numerous occasions where using 3-7-7 (or any given input for that matter) will give you nothing, nada, no wins.
What I'm trying to say is, a system that generates the same set of numbers for a given input, is like saying that the pick 3 lottery (or any lottery) has some sort of uniformity or consistency, which it does not. A good system is a system that doesn't generate consistent (same) sets but instead is adaptive to the situation.
