well, you are right. However you should take into account that
even in cbq the weight is not precise argument. It influences
excess distribution but you will see some discrepancies.
The idea is nice - only implementation is a bit more complex ;)

As I'm working on new version I'll try to do it - if it will not
slow things down.
It is because with assmption that "weight" is proportional to rate
we can make some algorithms faster ...
We will see ;)
