From the days when my travel agent taught me these things, a number of 4 or above meant "at least" .
So Y4 meant: at least 4, and could be much more
and V9 meant: at least 9, and could be much more.

And to the person who allowed one industry source to be mentioned in a post above, and seems to have removed mine which recommended using a(nother) industry source, please consult your internal ethics committee, or send me 10%
