tsr
Total Shots Ratio (tsr) is a means of expressing the number of shots taken by a team to the number of shots condeded. Theoretically, more successful teams should have higher TSR's.
TSR is a very simple calculation. The number of shots created by a team is divided by the numbers of shot created plus the number of shots conceded.
TSR = (taken / ( taken + conceded))
Getting started
Install the module with: npm install tsr
Require the module in your js: var tsr = require('tsr');
TSR takes two arguments: shots taken + shots conceded. You can pass in either numbers or arrays.
;; // 0.5; // 0.25; // 0.25
There is a fantastic overview of TSR and a few more complex alternatives over at 11tegen11 that you might want to check out. Thanks @11tegen11
