Glad I'm on the list! :D :D
I guess trying to order it do as shorter hops as possible would limit how many people were paying lots of postage, as well as the POs chance of losing them. I know in the current IRR my group has meant the tops cross the Atlantic 4 times, going between US and UK. I guess it could have been ordered so it only had to cross twice, although I have to say that I dont regret it since the different contributions people have made seem to look so right in the order they are.
