One area I had given thought to was to isolate the distance between appearances of each number... not average (that won't help) but full lists of such information for each digit in the pick 3. (Where paper play is always free)

If they are displayed in isolation, that could be a helpful indicator of how each individual number appears in relation to the noisy full result stream. When placed side by side, perhaps there may be some unseen order to these distributions.

Or maybe not. This seems like a good task for SQL querying... or maybe the raw power of pandas?

Then there is the layout, a number to indicate distances between digits, but also a way to indicate and highlight repeated digits. And deciding the output.. oldest first? Newest first? And the visualization... how to see the digit road map side by side with all other digits...

I have a feeling that diving into bioinformatics will yield some new techniques.
