This has NOTHING to do with shifting. And it can happen with any clutch based system. It is a throttle based driver in the loop occillation. And most times does not occur when shifting at all.
Driver steps on the gas, car moves forward, quickly, and driver moves back in seat, lifting foot from throttle. Driver pushes more to keep accelerating, but by the time the foot moves, the car has slowed and the driver moves forward depressing throttle, combined with foot movement makes too much throttle. Driver lifts foot, but body is moving back due to acceleration and lifts, combined with conscious lift lifts too mcuh, and so on, and so on.
Cure is to lift, or upshift. Basiclaly stop trying to catch up with the car.
