    Ranking Weight
AI Thread Summary
The discussion focuses on developing a formula to weight the "12 Month Median Ranking of Opponent" in tennis player statistics. The goal is to adjust the significance of the "12 Month Service Points Won" based on the opponent's ranking, as a player achieving the same service points against a lower-ranked opponent is considered to perform better. The user seeks a method to quantify this difference, ensuring that the statistics reflect the quality of competition faced by each player. A clear formula is requested to incorporate this weighting effectively. The conversation emphasizes the need for a more nuanced approach to evaluating player performance in relation to their opponents' rankings.

I have the following table.

I would like to know how to give an weight to the "12 Month Median Ranking of Opponent" so it changes other two columns depending on how high/low the ranking is.
To put this into perspective, this is regarding tennis players. On the spreadsheet I can have two players facing each other that have the same "12 Month Service Points Won" of 40%. Although Player A has a "12 Month Median Ranking of Opponent" of 300 and Player B of 100. Although the percentages are the same the player who managed to get a 40% "12 Month Service Points Won" against an "12 Month Median Ranking of Opponent" of 100 is extremely better than Player A that managed to get the same 40% against a "12 Month Median Ranking of Opponent" of 300.
I would like a formula to tackle this issue.

Let me know if I wasn't clear on any of my explanation.

I would like to come up with a formula that takes the ranking of opponent into account, giving more or less value to the other two columns.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
