names on paypal tranfers

[flybird 0]

How "analytical" does one need to be regarding the fact that some documents don't have both of our names on every page, but sometimes only on a related or subsequent page?

Consider evidence of comingling of financial resources as paypal transfers. A key paypal history page does not list each of our names; it lists one name and of our email addresses. Another "summary" page includes just email address. We can each print our "settings" page that lists are names with our email address, for that to be used to allow them to match the email to the name, but this would require them that extra analytical step. Since the pages are not to be stapled (and the order of pages might be altered), and since (I presume) one can provide only very limited "instructions" for how the logic works, how do I know they will see what we see? If this is deemed messy or burdensome for them, should we consider just dropping this transfer, though it was a significant event in our comingling, and go with the several other transfers that were made by bank (not by paypal)?
