Sorry I'm not following your question? Are you asking about the alternate digit representation? I hope my posting of this alternate view is not confusing to people. If it is then I will refrain from this action. My intent is not to confuse an already difficult task.
In my alternate string representation the most likely value for the first number is 11 or 12 which implies digit 1 hit 2 or more times, or just 1 time. No big revelation their so you have to move on to the next number and do further analysis.
My suggestion for people is if you take on a filter then try and understand everything about it.
For example using DO as a filter the numbers are 11, 13, 15, 17, 19, 31, 33, 35, 37, 39, 51, 53, 55. Ask yourself what is the relationship of this filter with other filters and write them down. Systematically examine each other filter and see how its effected with a DB value of 0, 1, 2 ...
For example if DO hits then Digit 1 or Digit 3 is going to hit also unless its 55. In addition TB in going to be effected. These are the relationships that will make you an expert on a particular filter. I would suggest using Excell or engineering graph paper and map out the analysis. If everybody specializes on at least 1 filter I would think the team is making great progress in the knowledge game but not necessarily in the overrall game. But you have to start some where.
As an example I work at company writing software that is a client server model. I do the client portion and know everything about the client. Another team does the server portion and knows everything about the server side. Each team unit tests the hell out of each piece and as indivdual components they work flawlessly. All this doesn't mean when you combine the client and server together that their are not going to be problems as a system test. There is and probably will be more time needed to integrate the components together as a system. But if the two teams communicated as they went along this should not be a daunting task because after all their both experts on the individual components.
I think we will have to go thru the same process of becoming experts on individual filters and then have the same growing pains of integrating them together because some filter values are going to conflict with other filter values and a decision will have to be made. I know everyone is excited but like I tell my managers I would rather take the time to design something right the first time than rush to complete something that everyone knows is going to cost more in the long run to support.
Again those are my two cents, I'm not intending to discourage anyone, in fact I'm trying to encourage everyone to learn. This single thread has become rather unwieldly. Maybe Winsum should pick a filter for the team to analyze, start a new thread and have everyone chime in on the relationships. At the end we should completely understand everything there is to know about that filter. That thread then would act as a template for how to figure out the relationships for the other filters. At that time I think each individual of the team can go do the analysis for their filter and report their results in a separate thread to present their research/analysis and have group discussion. This would be similar in my profession of having a code review of the software just written.
I know this is a very systematic process and might be boring to some people but I know from experience this works for my profession. Most of the software algorithms used in my profession were created and designed years ago. The creativity of software is taking an existing algorithm and making a small incremental improvement to it to do something else that no else envisioned doing. This process is repeated over and over in my jog. Unfortunately you cannot make small incremental improvements if you don't completely understand the base algorithm and are treating parts of it as a black box. Black box means you cannot see the inner details of how something works. From my experience this is always a bad thing.
Wow I just read thru what I wrote and that was boring so maybe you want to put me on IGNORE my feelings would not be hurt.
Anyway off to Park City for some enjoyment.
