While it is possible for the rev rate to be higher in the first 15-20 feet, I don't think it is a common thing to occur.
If you throw the ball at 18 MPH, your rev rate would have to be in excess of 700 RPM for the rev rate to be highest in the first 15-20 feet, than for the full length.
Again that assumes they haven't flooded the lanes the full 60 feet, gutter to gutter.
