Thanks Oli.  I made some changes, let me know what you think....

Is CIR 128k in this policy ?  if so, then is this correct ?

128k = 128 * 1024 = 131,072 bps

Then you mentioned default burst is 100ms worth of CIR... is this correct ?

100ms worth of CIR is 131,072 / 10 = 13,107.2 bits = 13,107.2 /8 = 1,638.4
bytes

If this is all true why does it still show 1598 bytes instead of the new
burst value of 1638 bytes ?
