What does the warm up stroke have to do with the hit on the cue ball? When Stan hits the cueball he is hitting it dead center, or incredibly close to dead center since we can't actually see the tip on the ball at contact.
I think you're chasing a unicorn here on this.
For one thing as Colin CLEARLY showed the shooter can swoop and add backhand spin and STILL make the ball when the dead nuts perfect shot line for center ball is plotted, marked, known and used 100% for each taken.
So even if Stan was a tiny bit off center in the delivery, which he wasn't in my opinion it likely wouldn't matter and certainly isn't gearing the object ball into the pocket.
You found that in a warm up stroke the shaft near the joint came off the line you drew on screen slightly. What does that translate into at ball contact? Nothing because at ball contact the cue came straight through the ball. But the overall point is that the butt of the cue can rotate like an egg when stroking and still come through dead straight on impact.
My video rebuttal is still uploading -

I went frame by frame in it to illustrate what I see.
Your video doesn't work.
About 30 pages ago I said I was interested in debating the subject of CTE, but only if you were going to be intellectually honest and follow the evidence where it leads. You gave me a pretty indignant response.
When I started posting the video of Stan's stroke I was surprised that you thought it was great. You made the comment that any investigation that can prove how CTE works would be great. This was a red flag to me because I'm interested in finding out whether or not CTE works as advertised, or if something else is going on. After I point this out to you, you agreed, I think, that we should follow the evidence wherever it leads.
OK, so what happens:
1. I post a video that I don't think has ever been seen before and I put it out there for people to inspect and see if I've done something wrong.
2. You make a rebuttal video (great!) and dispute my finding on the first CTE shot.
3. Using your rebuttal analysis as proof, you immediately post multiple times that CTE is confirmed even more because Stan swooped in the first non CTE shot, but shot straight in the CTE shot.
4. Within 24 hours, I post a new video affirming that Stan's CTE stroke is misaligned during the shot, refuting your assertion.
The problem here is that in good faith (at least on my part) I'm putting information out there for people to debate. Instead of allowing me or others the time to scrutinize your findings, you go off and tout your discovery.
What I thought we were doing was trying, first, to come to an agreement on what we were actually seeing. Learning what that actually means is a whole other (and more difficult) subject to tackle. But how can we hope to make any progress if we begin making interpretations of the data
before we even agree on what we are looking at!
I have since found a video of you at Stan's house for 3 or 4 days, touting your visit as the most important experience of your pool playing career. I'm glad you had such a great experience and I'm not knocking it in any way. This video, however, made me realize that you may actually simply be looking for new ways to show how CTE really does work as taught, and not really looking for evidence of how or whether in reality CTE works. In short, I think you are a full on cheerleader and I don't think you have it in you to be impartial.
I have several other instances on video of Stan pulling his hand in at the backstroke, and AFTER getting his CTE alignment. This quirk is just something Stan has ingrained and he isn't even aware of it. He shoots so well you'd be crazy to try and fix that flaw. I don't think there is much point in posting any new videos based on what I am seeing, unfortunately. We're just going to end up at "I don't see any flaw in Stan's stroke and even if it is there it doesn't matter anyway because CTE isn't affected by a cue motion like that."
Nobody can say I didn't give it a good try!
