The proximity measure seems to be flawed.

If you want to see how close to a non-ordinal 123456 a random generator can get, you also need to look for stuff like 923456 or 123956, etc.

Also, would 223456 be considered a closer match compared to 323456? (It shouldn't in my opinion because, again, these are non-ordinal strings).

If its a random ID then I'd argue that all of them are equally close to each other. With that said, I do not know how GUIDs are generated
