I've also looked through quite a few videos and pictures of cat launches and so far have only found one which shows a rapid undercarriage retraction so I guess, as correctly stated above it was only used occasionally.
I believe it was found with the Mk2 automatic retraction, or too swift a manual retraction, after launch led to some interesting aerodynamic effects that led to the loss of an aircraft. And then a second one when a test pilot went to show the squadron what they were doing wrong.
Possibly from the Victorious around '66?
