        aha... so taking a peek at my nearby BT tracker & client, it seems
        that there is abt 12% "duplicate" traffic.  

        wildextrapolation -- poor caching design/flaky networks have a 10-15%
        extra traffic load, "just to make sure".

        i'd guess that 10% of a femto (or is it the other way) byte of traffic
        relates to real money.
