Try to make it look like I said - back off from 256 ceil, make rates add 
up to master rate (220), give interactive more rate than it will ever need.

Class 24 does not make sense to me, and you may also find that ftp goes 
to default - It can be hard to mark and I can't see how you are marking it.
