Dan, for the donuts I could go take a picture, but I put those down pretty carefully while looking at the book. I would say that spotting the alignment line probably has larger error bars than my donut placement.
sent you a pm.

Cheap balls. Friend calls them 80 grit balls.Contact induced throw. Well thats my guess.

As sixpack stated, "english" induced. I was specifically referring to throw caused by friction at the point of contact due to being too close to an ob and shooting firm enough to cause a stun shot.
I like using the word PUSH better than throw, because that's really what's happening. English throws the ob left or right off the shot line, but the collision pushes it off the shot line. Oh well, I guess "push" is already defined in the pool dictionary and that settles it.
John you're right I was not finding my shot line before getting down on the shot on that video. I am also short-stroking and hitting a bit light trying to reduce variables. The results are consistent whether I am headed toward the left or right corner, so at least whatever I am doing is symmetrical.

This clip should help with fine tuning your fractional aim. Figuring the fractional aim point mathematically is usually not necessary. Instead, use simple visual references, comparing basic aim points with the exact shot setup you have. Like so......

Simple to learn and deadly accurate. What more do you need for learning how to aim?
One question though: What do I do if I don't have three cue balls? :wink:
Lol. I think every player should carry extra cue balls in their case! (Just kidding). Here's another clip using the shaft instead of extra CBs.....

Nice! I've got a question I like to ask good shooters: Every pro I have heard from says to put a touch of helping english on the cue ball for every cut shot, like as little as 1/10th of a tip. This keeps the ob from skidding along before achieving natural roll toward the pocket. On the other hand, many instructors say NOT to do this, and to use only the vertical axis for cut shots. What do you do?
I naturally account for a normal amount of throw by aiming a touch thinner on cut shots between about a half ball and a 3/4 ball thick. It wasn't until I came up with Poolology that I realized I was doing this. And so I figured this natural way of dealing with CIT into certain alignment values for the system, which means a typical amount if throw is automatically accounted for in the same manner as I naturally do it -- slight overcuts on certain angles. The only time I use a touch of outside/helping spin is when I expect more throw than usual, like a stun shot or slow speed on thinner cuts, etc...
I'll put you down as a "no." I play the same way, but I have to say the helping english is creeping in here and there. Two reasons: 1) Two HOF straight pool players personally told me this was very important to do and the best way to play, and 2) You really can see a striped ball slide for 6 inches or so before rolling if you pay quick attention, vs with a smidge of outside the ob rolls more cleanly right after the collision.
