Cisco rate-limiting and burst values on 3560 v12.2(55)SE3

I want to rate limit traffic on an interface to no more than 80Mbps.  What I am not clear on: what do burst-normal and burst-max parameters do exactly?  Thanks.

int gi0/48
rate-limit input 80000000 40000000 40000000 conform-action transmit exceed-action drop

These are just the amount of burst data allowed to go above the rate limit you specify, so burst normal is the amount above the rate, and burst max is the amount above burst normal.
