My point is that when there's maximum top spin on the cue ball, you can literally see it spinning forward once it stops sliding. You're applying plenty of force to the shot, but I'm not really seeing the driving topspin. I'm not sure what adding another blocking ball, as you suggested, has to do with force follow. I don't see it that way. What you're showing in that shot is a change of direction which I think is taking a lot of energy from the shot, leaving nothing much left after the change of direction.

to me making the cue ball have enough follow to rebound off the cushion and then to have enough follow to bend the cue ball path back to the rail is what many would call force follow force .
if the object ball was hit more thickly the bend would happen sooner and the cue ball would stay close to where it hit the object ball
if the object ball was hit much more thinly the force of the rebound would be stronger than the follow so the cue ball would bend back little if at all
denwits shot is learning to blend the thickness of hit to get the bend to occur where he wants
based on your stroke the more rpms you can generate on the cue ball
the farther off the rail you can get the follow to overcome the rebound force
thus determining f you can do 1/2/3/4/5 balls as blockers
thats how i see it
lastly
for me force follow is maximum high with alot of force
causing the cue ball to appear to turbo charge forward
in reality you are seeing the transition from slide to when the follow kick in
