Hey, talking about stepper motors here is borderline; talking about that other thing is over the line.:)

Oops... sorry. At least I didn't mention delay lines... or CAMAC crates....... or, heaven help us, wire wrap guns.

when you sight the cte line first you have to adjust your eyes/head position to sight the aim point on the ob- a,b or c.this gives you a different perspective of the cte line

What does "a different perspective of the CTE line" mean? Are your eyes still on the CTE line?

Remember that in most cases your eyes can't be on both lines at once. For instance, the CTE line and edge-to-aimpoint B line are parallel, so they don't share a point. So exactly where are your eyes supposed to be?

Personally, I'd call "Pat's CTE" (which I think would be a good thing for people to try, by the way) "exact". It has a clearly defined procedure that obviously converges to a stopping point that is sufficiently precise for its purpose.

Pat's CTE is an intentional example of the opposite of "exact" as it's used in these discussions. CTE users have claimed that CTE describes a series of precise steps that can be followed robotically, without deviation or any "input" from the user, to arrive exactly at the correct aim for each and every possible shot. Pat's CTE uses almost nothing but user input.

If we're going to talk about "exact" then it needs a clear definition, and one that is careful not to exclude things that should be kept in. I'm not too interested in that. As far as I'm concerned, "exact" is what you worry about with, say, stepper motors and the wire spacing on proportional chambers used for xray crystallography, not pool.

Wow, this brings me back. In college I worked for a chemistry professor who actually had a xray crystalography machine, he was interested in having someone write code to drive the motors to perform his experiments. He gave me the manuals he had and I wrote the code for him. Eventually his experiments were selected to be included in one of the space shuttle launches, don't remember exactly what zero gravity had to do with what he was doing but I remember he was pretty excited he was selected.

Sorry, just had to comment, think it's been 25 years since I've heard the terms xray crystallography and stepper motors... :)

for me i start off on the cte line then i move to the edge to ob aimpoint line.from that position i see the cte line from a different perspective.you could say a new cte line as its coming from a different edge at the new perspective.
the way it works for me if my eyes are on the aim point line looking at the cte line.my whole eyes/head/body either rotates or moves depending on what pivot is required(offset of new cte line) to the make the shot.
its funny how something has become pretty second nature is difficult to put into words.
i'm right eye dominant and ive tried doing the process with my left eye shut.i doesn't look right to me,i dont seem to see the same perspective/lines.only with both eyes does it work consistantly for me.

The CTE line cannot "come from a different edge". If you don't see this basic fact, then we can't discuss this stuff meaningfully.

Thanks anyway for trying.

Only because your such a slow learner. Are you being stupid on purpose?

You're free to explain what "your eyes offset the CTE line" means, cookie. Go ahead, give it a shot. It'll be the first time I've ever seen you try to actually contribute something.

pj <- any bets?

I don't have to make fun of you guys - you do it to yourselves every time you post. Wanna prove me wrong? You can explain how the CTE line can "come from different edges".

I'll wait.

do you own a pool table pj?

We don't need a pool table for this. That's like saying we need a pool table to explain why we can't see around corners. Either you know or you don't.

Regarding using the exact cut angle:

I'll get back to this later. I touched on it briefly in that long mess I originally posted, but it probably deserves more discussion.


To have a different cut angle, either the OB or CB or both must have moved from the original position(s). If the player doesn't move (realign) then the original visualized CTEL and A or B or whatever lines are no longer visually in the right place. He is forced to move to restore the correct visual alignment, which causes him to find new CTE, etc, lines. Below is a picture; it's not in perspective, but the principle holds. I haven't figured out how to type below an attachment, so I'll have to do it here.

In both cases, we have an outside CTE line (the red line) and a left-CB-edge to OB B line (the green line). The ball with the roughly dashed outline is the ghost ball. Clearly the shots go at different angles. I probably should draw this out in 3D where the orientation of the table top on the screen would indicate the player's alignment.

In your diagram below, let's use the top example! Not moving the balls from thier original position, if I wanted to shoot this shot let's say at the third line up from the corner. Would I not have a new CTEL to align to?

What you looking to bet PJ, I'll call your bet. But since your out is always "we don't speak the same language" lets get one of your homeroom buddies to judge the answer.

what is wrong with you? you seriously have problems lol have you ever held a job in your life? have you even left your house? you have brutal social skills!!! actually it seems like you have none at all? wtf?

I was betting you'd never risk trying to actually contribute anything tangible.

So far I'm a winner...
