It's not necessarily a bad thing at all. In fact, it is quite a useful command much of the time. If the task said to configure such and such percent of the bandwidth I would first set the bandwidth to the line speed using the bandwidth command. Then, I would set Max-reserved-bandwidth to 100 to make the math easier. If you do "bandwidth-percent 20" with the default "max-reserved-bandwidth 75" what you are getting is actually 20% of 75% ...to me that is more difficult. If you set max-reserved bandwidth to 100, you actually get 20% of the entire interface bandwidth.
