A deep dive into the Performance Alpha Engine: From Chemical Kinetics to JEE Percentiles.
Exponential Interpolation: Unlike linear models, we treat rank as a "reactant" that decays as marks increase, modeling real-world student clumping.
Localized K-Constants: Every 25-mark bucket calculates its own unique 'difficulty constant' based on the ratio of logarithms ($ln$) of the top and bottom ranks.
Delayed Gravity: A quadratic runoff (t^2$) ensures a smooth transition at the 80th percentile and an accelerated drop-off near zero marks.
