In heavy stuff the boat stops right away so you need to get all you can out of your boat momentum without pushing so hard that the rudder stalls. Just a touch of delay moving the jib over is all you should need. If the boat doesn't start to take right off don't forget to reverse the rudders when you start backing up.

When the wind is light to medium you can sail the jib through if your touch on the helm is good.

I haven't watched Ricks video. Was it on board boats or 16's? Board boats shouldn't need the jib at all to get through a tack.
