That is great for dead center hits! Now try the same drill with low right.Not how I practice (that might explain my game) but after watching the video it’s kind of cool!
I like the swinging pegs. As a stroke check I set the cue ball on the spot shooting at a piece of chalk on the middle diamond of the rail and get the cue ball to return to the cue tip. You could use this in the same way, just like a carnival game, don’t get the pegs swinging.

That's what the Aiminator enables you to practice. Using any type of tip placement on the cueball and be able to split the pegs without hitting them thus making the shot.
