I think 'over 7000' is a reasonable statement. It is saying in effect that the FO was not a newly qualified pilot, the likelihood is that the captain had more but that doesn't need saying as this is a 'good news' message about how well they did.

When this type of statement is made it usually means they have LESS.
Sorry, this is a con
