(In reply to No Subject by brianjn)

I hit a wrong key which posted my prior comment.

Ady (elsewhere ) had queried the value of the first place after the decimal point, hence the extended listing; every digit shows somewhere in that place.

In case it was missed, I included a skeleton thought of an early attempt to arrive at a solution using Excel.
