The way ATL is set up, doesn't matter so much how many terminals you have to travel. Most of the travel time is between gate to/from the train, not time ON the train.
It depends on your fitness level. The trains can take longer than you think with all the stops. I had a 15 minute connection from end of concourse A to the end of concourse E. It took me about 13 minutes and I think a good 6 - 7 minutes of that was on the train (each stop felt like an eternity as I waited for the doors to close up). It's still faster than running (except the stop from D to E which I think I can outrun -- it's really short), but don't discount the amount of time it will take. Naturally, they had cleared the standbys and closed up early by the time I arrived for my flight.
