 In researching this concept, I discovered numerous values and coefficients scattered throughout the community, each employing different mathematical approaches. While many in the community describe these calculations as "good enough," I found them often constrained by linear functions, lacking the dynamic scaling needed to accommodate variations introduced by Blizzard throughout the expansions. Many stats vary based on Inventory Type, Quality, and Item Level. 
 
-Improving the accuracy of these calculations hinges on enhancing the quality of the equations. As a first step to the conceptualizing this calculator, I immediately found the need for a method to more easily plot and graph data. So I developed a graphing tool called [Polynomial Visualizer](https://github.com/dewmguy/PolynomialVisualizer). I used it to draft many of the formulas the calculator uses, the formulas and the links to their data are scattered around down below.

 Stat and item level calculation accuracy significantly improved by introducing polynomial regression and categorizing formulas and coefficients by item quality and slot according to their appropriate item level ranges. The enhanced equations integrated into this calculator provide significantly more reliable outputs, closely reflecting in-game values. Though it is far from perfect, testing reveals that the calculator typically deviates by one or two item levels from actual values.
