Good idea! It already looks good, but what about:

   |-- 1:2 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b
   |      |-- 1:40 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b
   |      |-- 1:50 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b
   |      '-- 1:60 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b
   |-- 1:1 (htb) prio 0 rate 1Kbit ceil 6Mbit burst 15Kb cburst 1599b
   ...

just another idea..

Thanks.
