i hope this helps a bit and i hope im close to being correct because i just did a quick brain storm on it and also you do realize there are 2 different reference points on those shots? Im guessing your at the beginning stages of learning the system?
When you are behind the cb/ob on that first shot you have shown (straight in the side) there are 180 ticks on the ROUND cue ball and i guess 180 contact points on the object ball you are now staring at. Now you have to find center cue ball and that is 1 out of 180 ticks on the cue ball.
Me personally i am probably in and around the 85-95 tick spot when looking for the ctel, dunno and don't care, i am also experienced.

if you walk around the cue ball you will always have 180 ticks staring at you...get it?
This is how i see it and i can make that shot in the side 20 times in a row and i doubt im on that exact tick on the cb more than a couple of times at most. <<<< this is tip!
The left eye aims for left cuts during ball address to an OB aim point. The right eye aims for right cuts. The eye function of aiming is retained all the way into full stance and final aim at center CB <<< tip! this took a long time for it to sink into my skull!
i could so make all this easier to learn for you guys...but i constantly get trolled and its even the cte guys doing it now lol
