MC9S08DZ60CLC Sector Erase Time

My application requires a fast sector erase/write time to function as a counter.  The measured erase/write time on my MC9S08DZ60CLC has been consistently about 3ms, however, the datasheet (p. 53) states that a sector erase by itself takes 20ms.  How is this possible?  Did I miss something or does the microcontroller perform better than it's supposed to?
