This is what I do. I set up a wide variety of bank shots, sticker them, then shoot at different speeds, different spots on the cue ball, and with different spins. Thats how you figure out and remember the various effects.Most bank methods give you a method to find an angle and target which you must then learn to cinch. A more thorough way is to shoot at specific targets on the rail ( just like pocketing balls - go figure) and learning your ranges and margins.
