How to adjust for banks close to the rail?

Dr. Dave's, "1/3-more-than-twice" diagram,

If you can't find the spot on the wall, Dr Dave has replaced the '1/3-more-than-twice' with a 'twice-plus-tenths' calculation:

Set up a mirror image target. Find the line for a straight such bank that sits at 2 from the end rail. Extend that line forward until it hits the extended end rail nose. The intersection is the target for all cross-corner banks that are sliding. The point is roughly three diamonds from the side rail rail nose along the nose line of the end rail.

Of course this does not include any side spin you get on the object ball, but it does give you a starting point for twisted shots.

Thanks Bob. I just set this up using 3 different angles and made 3 in a row. I could not believe it. Then tried more variations and was pleasantly surprised. You are amazing.
