no secrets, just practice and figure it out.
It would be really nice to have a path to study one proven method that reallly works for all bank shots, or maybe to know that there isn't just one method that fits all.
For me it's practice, practice, practice. I don't generally use diamonds for one rail banks. It's like muscle memory. I can bank a long shot easier than making a cut most times. In the early 90s I'd play bank the 8 with a friend to make the games last longer. Banking became easier than cutting for some shots. I'm just a barroom player with no fargo rate and only a few tournaments in my history. I feel, sometimes, I can "see" the bank automatically.but have no consistency at all.
It is not the speed itself that shortens/lengthens banks. Many players don't understand this. It is the spin on the ball hitting the rail that changes the bank angle. How much follow does it have going into the bank?.... What was never mentioned (that I saw) in this entire thread is the speed of the bank makes a difference...hard narrows...soft widens......so unless you are hitting medium firm on all banks...you can throw out the "perfect angle" methods...
Yes, this is the hardest part of banking.Another point for the OP to consider is that if you get spin on the object ball, it will change the bank angle and can be more than enough to miss (or make) the shot. Here is a demo of this idea. The eight ball is on the spot. The nine ball is exactly in the middle of the normal bank path. By using left or right side spin on the cue ball you can get right or left side spin on the object ball and then bank the eight ball on either side of the nine ball and still come back to the pocket.
Sometimes you get side spin on an object ball just by it being a cut shot. In the diagram, you put side spin on the cue ball to transfer some to the OB.

I like your formula. Do you use it when banking or normally use intuition? Please do not consider this a negative question. I think most bank pool players use intuition...but I don't really know.For the example on the left (kicking to the corner pocket):
- The CB is 2 diamonds "vertically" from the kick/bank cushion, and the kick/bank cushion is 4 diamonds "vertically" from the target - so the CB's total "vertical" travel to the target is 6 diamonds, and the CB travels 1/3 of that total distance to reach the kick/bank cushion.
- If the CB travels 1/3 of its total "vertical" distance to reach the kick/bank cushion, it must also travel 1/3 of its total "sideways" distance (parallel to the kick/bank cushion) to get there.
The fractions of the CB's "vertical" travel distance are dictated by the position of the CB and the target. The fractions of the CB's "sideways" travel distance are chosen to match the fractions of "vertical" travel distance.
Hope that helps,

For one- or two-railers I use intuition informed by parts of different systems/measurements. More rails than that and I'm just guessing.I like your formula.
