Making Data Objective

On the Quasisubjectivity of Pool Stats Data Collecting

ABSTRACT: There have been a few outcries on how we handle our data collection. Mainly, there is a notion that our data entry is subjective and will not generalize to a larger degree of players. This paper seeks to address these notions about how we handle subjective input and the policies, guidelines, and algorithms we […]

A Word on Shot Aptitude

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 […]

Update: DSR (Defensive Success Rate)

http://poolst.at/dsr We have made a small adjustment to the calculation of DSR (Defensive Success Rate). In the following press release, you’ll see that we have added a new variable to account for the missed shots by an opponent after a player plays safe. The missed shots is weighted as to not give it the full […]

DSR (Defensive Success Rate)

http://poolst.at/d We’ve devised a new sabermetric for pool. DSR measures a player’s ability to play safes effectively. To gain an understanding of the metric, we’ve published the formula. In easier terms, a DSR > 50 is highly effective. A DSR > 100 is extremely effectively, and illustrates that you force more turnovers, via fouls, than […]

Average Consecutive Made Shots Per Match For All Players Recorded

Here is a nice scatter plot illustrating the average consecutive made shots for an entire match fro all players. Basically it compares the players matches, that we’ve recorded, and how often they stay on the table, i.e., consecutive made shots without missing. Below is the image and interactive graph of the stats.
