There has been minor controversy surrounding this stat. Mainly gauging a player’s ability with regards to time. It is true that while time is a major factor in these equations, it’s not the only factor at hand. More goes into these equations than simply time. Time is a weight, like any other measure. Also, since every player will have shots they spend more time on, the sample size levels out on the whole.
Most mathematical/scientific innovations and statistics don’t find practical use at the start and can take years to achieve maturity. It’s only until someone realizes what they can benefit from it that it becomes a socialized norm.
You use pool stats as a gauge of your ability. We don’t all need to become Filler’s or Shaw’s in aptitude, but increasing your aptitude will improve your game and conversely as well.
How does one increase their shot aptitude and how will it help you?
That list isn’t comprehensive, but, do these things and your shot aptitude will increase. Use shot aptitude as a guide not as a ranking, but a ranking it also is.
