EGR Drive Cycle

Hello all my name is: Kane
I have a : 1999 3000GT Base
It has the following issue: Drive cycle is not finished and EGR is not ready, and I have driven it about 300 miles, with plenty of stop and go’s. Mainly drove at 50/55 mph in 5th and 40 in 4th, as that’s what people suggested on other forums, does the drive cycle for EGR normally take that long? What are the requirements for the EGR?
