that is easy, on cruise the acelerater petal is in constant movement to hold 65, on 70 - 75 you keep your foot in one place.

You'll see this! It's pretty common , more so in the Big trucks!

As a matter of fact, Most of the new electronic Cat and Det. motors have different fueling and timing curves on cruise!
