Parachuting players glitch up and down very quickly when falling

[AndrewTheel]

Viewing a player who is parachuting, the player and parachute will glitch up and down very quickly while falling. It seems to smooth out once the player is 10m or less above the ground. Basnett thinks that the client is either unaware of some movement/speed change or is running its own and as the server corrects the actual location you see a strange and quick jump in the movement. Fixing this will make parachuting look much smoother.

A good place to start looking would be the client-side Velocity and Acceleration values for the parachuting pawn. My hypothesis is that the velocity might be consistently higher than it should be when this bizarre behaviour is observed.
