John, first, let me thank you for sharing that.
You don't have to sell me on aiming systems. I have my own, you'll remember, which -- though your vinyl-playing needle seems to be "stuck" on ghost ball and repeats it with a click over and over -- doesn't rely upon seeing a fully-formed ghost ball. Rather, my method is melded from back-of-ball and fractional aiming. My method is based on memorization of easily-recognized fractional ball overlaps, or "eclipsing" as I like to call it:

It requires work, sure.
Lots of practice to commit to memory how each fractional "click" (each incremental increase in cueball-over-object ball overlap) sends the object ball to the next angle in the lookup table. Once that lookup table is memorized, though, I can see these relationships on the table instantly, and, like CTE/Pro-1 visuals, I zoom in right on them as I bend down into my shooting stance. The nice thing about this, is it's NOT CONNECTED TO A POCKET. If I "want" to connect the visual to a pocket (as is usually done when wanting to pocket an object ball), I put the pocket in the visual picture, of course. But, if I want a bank, I just visualize the bank angle (to include any CIT or spin I want to apply), and <click!> the fractional overlap / "eclipse" visual appears for me instantly.
Another nice thing is that this system is not connected to the dimensions of the table. It's purely ball-to-ball cut angles, tied to a "reference angle lookup table" that is memorized. I don't care what "shape" the table is; I just see the angle and the amount of "eclipsing" I need to do with the cue ball over the object ball to send the object ball down that angle.
I liken this system to multiplication tables that you had to memorize in elementary school. It was a lot of work (and it sucked, as most kids will attest to), but once done and committed to memory, you can "see" and spiel these results off at a moment's notice. Except in my case, the table goes backwards -- I see the angle to the pocket (as I'm standing upright), and then I see the amount of fractional eclipse I need to send the object ball down that path. Once I see that amount of fractional eclipse, I don't need the pocket in my field of view anymore.
Would I be able to reproduce Stan's results of being able to pocket balls while the pocket itself is concealed behind a curtain? Probably not -- I *do* need to see where the pocket is
while I'm standing upright. But once I have that fire control solution locked in (i.e. the amount of fractional eclipse I need between cue ball and object ball), and I've dropped into my stance, sure, drop the curtain, and I can shoot the shot. This is roughly analogous to turning my head and looking away, which I do in lone practice sometimes to make sure my stroke is true.
Anyway, I'm not into doing exact replications / match-ups of someone else's aiming props (e.g. curtains). Because in real life, those things don't exist. What I am about -- as you know from my preference for 14.1 -- is pocketing consistency. Whatever it takes to give you that, I'm all for.
