Indeed. This is what happens in opencoin. You can rely only one doing at
least one payment before getting new change. I think you fully
understood it.

This is out of the scope of our system. However, is a refresh really
income? Because in the end 4 EUR are going to the bank, but also 4 EUR
are leaving the bank. So, turnover is increased, but not the balance.

I completely agree on pointers to the source as being inadequate. We
don't have formal spec for this bit though. But you have the idea, and I
will add a description of the refresh mechanism to the documentation.
