A reasonable approximation of backlog in packets is achievable by
dividing by 1000.


This only works for general internet traffic. It would probably confuse user with say VoIP gateways.

I think it's better (if we really want to go this way) to use the average package size of the past packages per queue by diving the sent bytes by the sent packages.

But I'm still not convinced, that this is the best option we got. How difficult is just a conter on the cake-side?
