taking speed into account

I don't post here much, coz aiming systems generally whooosh over my head
but I'm watching bugs rucker's bank pool tape (on youtube, fyi)
wondering if/how aiming systems take ball speed into account
or is speed usually considered an independent variable?

Are you referring to bank shots? On bank shots, speed can have a lot of effect on the angle of the ball coming off the cushion.

If you mean aiming simple cut shots, I don't think any aiming system takes into account the fact that speed changes the amount of throw on cut shots.

On bank shots, higher speeds can shorten the angle of the ball off of the rail. There are many aiming systems for banks that use that. For example, on many tables if the OB is near the center line (longwise) of the table, like within a diamond of the middle, if you aim to split the difference (halfway) between the object ball and the pocket you are banking at and hit it hard, the ball will go straight in the hole.

Especially useful for banking cross side.

Most ball-pocketing systems that can apply to banking (like CTE and Poolology) don't explicitly account for banking at high speed. For those to work you need to hit a medium/soft speed so that the angle of reflection is closer to the angle of incidence. There are adjustments you can make to account for it but they are not built in to the system.

I think (I don't know many bank pool specialists) most bank pool players know how to make certain bank shots according to systems or experience and have a feel for whether or not they need to shorten or lengthen the angle and do it by instinct.

I also think that most of the time they vary the speed to adjust the angle it is for position play or to avoid impeding balls. Good bank players don't need to rely on shortening angles to make the shot easier.

Aiming Systems don't take speed into account, you do.

my thought-stream a bit muddy
I was referring to aiming, in general
not just banks
that said, great replies!
thanks for them-

I don't know of any aiming systems that take speed into account for pocketing balls. CTE *might* but that is a controversial topic. :)

Yes, but there are some interesting exceptions. A ball on or near the rail banks shorter even if not hit hard, because it doesn't have time to pick up forward roll that would make it masse longer after rebounding. In fact, hitting that ball hard might make it go slightly longer because it rolls a little farther down the rail while rebounding.

Like everything else pool related, Dr. Dave has lots of good info about it:

Independent variable, like spin. In fact, except for the handful of "system" aiming alignments, the specific aiming alignments themselves are independent variables (i.e., not fully defined by the system).
