Formula required for rural pool league stats - cause we have NO idea!

[steveSGSJ]

Looking for a formula to calculate a pool player’s averages in a rural pool league….

We are a rural non-profit community organization that plays pool every Thursday evening. We have no interest in joining a ‘sanctioned’ league and funds do not allow us to utilize the on-line systems for team statistics. Doing what we can with what we have got.

Here is a quick look at what we are trying to do…

Players play a 9-ball match, set of games. Each pocketed ball (1 thru 8) is worth 1 point, with the 9 ball being worth 2 points.

Players have a skill level (S/L) ranging from 0 thru 10, in .25 increments. [6.00 6.25 6.50 etc]

The assigned S/L has a number of required points(R/P) assigned to it that a player must reach to win the match. The number of games determined by how long it takes a player to achieve the required number of points for his/her skill level.
S/L 6.00 = 29 points S/L 7.25 = 35 points S/L 9.50 = 45 points

Each S/L has assigned to it a static average number of innings (A/I) [turns at the pool table].
S/L 6.00 = 4.46214 S/L 7.25 = 3.15653 S/L 9.5 = 1.50900

Complete list of S/L – R/P – A/I is contained as a reference within the spreadsheet.

Tracking of number of games, total innings, wins, loses and defensive shots (D-SHOT) is documented by team-mates during each match. This data will be later entered into the statistics spreadsheet .

This data (mostly the S/L) is calculated for the current(tonight’s) match, as well as being applied to the player’s S/L rating for the current season… and applied against his/her lifetime S/L rating. (Lifetime rating can vary from 0 to 10 years of data) The weight of one night’s data is less with an increased number of matches in the current season, and the greater amount of data within the lifetime for that player, respectively.

For anyone interested, I can supply scenarios and a copy of the pool league stats spreadsheet that has been created so far.

Thanks to anyone willing/capable to help us out.

What is the question?

I have to agree with JeffM. I did read your entire post but you failed to ask any question!

 

[steveSGSJ]

And Jomo hates to agree with Jeff, almost as much as he hates agreeing with Denis.

Sorry, my original post did not contain a specific question. I am not 100 % sure that I actual have a "specific" math question, more the scenario of trying to calculate a player's skill level based on the data collected, as well as applying that skill level, or the data, to historical information for the same player. I know it will require a formula WAY beyond the capabilities of anyone in our group.

Basically we have various data related to a player's games... looking to have it reflected in a single skill level number. What goes between getting from raw data to that single number that represents the player's skill level is the question. This is where we fall flat on our faces!!

Maybe I am out to lunch, was looking at sending our spreadsheet, which is in the final stages of being created (minus the required formula) along with however many scenarios in an effort to have someone create a formula to calculate what we need. Assuming that additional correspondence would be required to verify and confirm both the understanding of the data and scenarios and the results generated by a formula.

BTW.. entertained by your humorous bantering of each other.

Basically, this is a question of weights. How much importance should be given to which pieces of data? This is a subjective question, not a math question. Tell us the relative importance that you agree upon, and we can give you a formula that reflects your collective opinion.

Thanks, I will see what we can come up with and post it to see if it makes any sense.
Would it be helpful to have examples?
