Do you have any pair of notes with consecutive serial numbers that were found some months, or even years apart? How far apart?
An easy way to check this is using the excellent statistics generator nigmm. The first part of its "Serial analysis" page is called Near notes / "Family meeting". Here's an example of what it looks like:
- lmviterbo on nigmm - near notes (family meeting).png (91.4 KiB) Viewed 1315 times
So, on the example above (from my own database), you can see on line 12. the consecutive notes "separated at birth" that have found their way to my hands 166 days apart (in different towns actually!).
So what is your score? If you have one line with 1 "note difference", how many days apart ("Days diff.") were they found?

[Note: I am not sure how rarely these pairs of consecutive notes are found. If too few EBTists have found 1-note apart notes, this game has to change. I have an idea on how to do it (instead of a single number, find your highest ratio "Days diff./Notes diff."), but I want to try the simple version before.]

I'll try to see if I can borrow a colleague's computer to do it.
