One of the reasons for the chute where it normally is, is to actually help get the ring off the hook.
If you do experiment, maybe have the chute at 2+ fuse length away.
If a pilot has a tendency to over run the parachute in a dive and the extension is not long enough, it could be possible for the chute to end up flirting with the tail more often than without the extension.
In an extreme cast the chute could be hitting the tail before the ring comes off... if the dive was too severe, no tension and in some wind etc. Just thinking of some instances I have been in to share
