I think you have to do *.75,,,
-- let me ask this way,,
so if you do "max-reserved-bandwidth 100"
What do you do?
I thinks you have to do *.75 unless you set the max bandwidth to 100.

Subject: RE: Converting Custom Queue to CBWFQ
IMHO, regarding the bandwith percent command; the 75% is given by the
command:
wp1001667Router(config-if)# max-reserved-bandwidth
percentBM_1001665BM_1001666
this command changes the maximum configurable bandwidth for CBWFQ, LLQ, and
IP RTP Priority
that by default is 75%; there is no need to multiply by .75.
so in the example below it should look like:
www - 3000/5500: 55%
dns - 1500/5500: 27%
default - 1000/5000: 18%
