Proofs of the EXACTNESS of Pivot Systems

Sorry, don't know what that means.
Kinda depends on what you're aiming at, doesn't it? CB edge-to-AorC is just a fatter cut than 1/8. Both of them aim the CB's center off the edge of the OB. Neither is better or worse in that respect.
More importantly, skipping A or C and going past them to 1/8 leaves an unnecessary gap in the available cut angles.

I believe this now correct? no wonder i could never make those 60 degree shots lol
So am I missing something or how do you do the exact same aim and pivot for 30 and 45 degree cuts?? I'm probably reading this wrong so if I am, my bad. If not, please explain your theory.
I don't list cut angles for each of the 6 lines of aim, so I'm not sure where you got those numbers. The exact cut angle each line of aim will create depends on the exact CB-OB distance and the exact bridge length used. For a given CB-OB distance and given bridge length, we could figure out the cut angle created by each line of aim, but I honestly don't think this information would be very useful.
The important point here is that 6 lines of aim will produce 6 and only 6 different cut angles. One difficulty is in picking the line of aim that creates a cut angle closest to the one you need for a particular shot. The other difficulty is: even if you do pick the line of aim that creates a cut closest to the one you need, the shot still might not go. 6 lines of aim is not enough to pocket balls over a wide range of cut angles from 0 to 90; although, the 6 lines will work for some shots, provided you always choose the correct line of aim from the 6 options for each shot.

Thanks for the drawing. I still don't know what you meant about CTE line and 1/8 line, but I don't think that matters. Your drawing does clear up one source of confusion for me - I now know that the "1/8 line" isn't CB edge to OB 1/8 but CB 1/8 to OB 1/8, which is just another way to aim CB edge to OB 1/4 (A or C thin cuts).
have a good look Pj cause i going to remove it as soon as u see it ok
Thanks again,

ok well i figured out what i was missing according to your table, that was the medium thin shot. Which would be ccb to robe, 1/8 cble to 1/8 obre with a right pivot if i understand your table?

what i meant was ccb to edge of ob and 1/8 on cb to 1/8 on ob, you figured it out and now you should be able to see that your not aiming in space, right?
Not really. They're both the same alignment, so they're both aiming in space.
Whether you aim CB edge to OB 1/4 (Stan advises against this) or CB 1/8 to OB 1/8 (Stan's recommended alternative), you're aiming the center of the CB at the same place off to the side of the OB. I thought that's what Stan didn't like about CB edge to OB 1/4, but since (I now see) CB 1/8 to OB 1/8 is exactly the same alignment, I don't understand why he likes one more than the other.

Stan system relies on you having a certain visual behind the ball, you need to figure out how to lock these two lines in your visuals, until you figure this out you may miss half your shots. Remember these 2 lines are putting you on the contact point of the object ball pretty much.
So when you pick up both lines, (its like getting a missile lock on a plane) once you get it locked in you just drop down to a right or left pivot and then pivot and shoot! and dont worry about where your cue is or should be! its either lined up for a right or left pivot!
Picking up the the two lines behind the ball is critical for this system!
ccb to robe with an A reference and a right pivot
This picture is visual of being locked in (missile lock), your next move will be straight down for a right pre pivot, no if ands or buts about where the cue goes! just straight to a right pre pivot position and trust yourself that you made perfect visual, its just that simple.
Stans system is based on having this visual behind a ball, this is how he designed it

I prefer a left to right pivot, as it seems to be more natural for a right-hander!! But both work!!
Wouldn't it look the same whether you're going to pivot right or left?

It will look the same with a left pivot, but the shot will change from a straight in (very little or no cut) to a very thick (more than a 3/4) cut to the left.
If you look at dr daves site, on his table for cut type and amount, these two shots are the first two he shows, straight in (very little or no cut) and very thick (more than a 3/4) cut to the left. if you have trouble understanding dr daves table, let me know and i will show you in terms that stan uses,example - ccb to robe, left cbe to A with a right pivot.
