1150 bare minimum with supporting documented data is great progress .
1550 approximation isn't an unfair number with that.

You were the one that proposed the Pattern Order Numbers were potentially a count of cars per Zone.
That was progress.
Determining there were no repeating interlopers in a given Zone adds solidity for sure.
Heavy progress.

If you have a chance to list each Zone - with it's highest Pattern Number currently on file ,,,,
John can check his files for any higher Pattern Numbers or any Zone you don't have a sample for.
And John and I can keep our eyes open for further cars that develop.

In some cases just one or two cars could bump the numbers considerably .
Thanks North !
