What is the difference between Maximum Torque: RPM vs. Gear and Torque Limit vs. RPM: Max Torque?

Both of these sets of tables have very similar definitions, but the individual max torque tables only go to 3000 rpm while the RPM vs. Gear table goes to 6400 RPM. I'm hoping to use these to set up a rudimentary launch control so I don't just blow my tires off every time I bury it from a stop.
