Rush

Spearman

\begin{aligned} K&=0.7\left(0.1+\frac{\text{mastery rank}}{10}\right)\\ P&\sim U(\min(P_0K,P_0),\max(P_0K,P_0))\\ R&=\left(J+\frac{aP}{d_P}+\frac{S}{d_S}+\frac{A}{d_A}\right)(W+W_{\mathrm{ammo}})\frac{p(n)}{100}\\ D&=\operatorname{clamp}\!\left(\left\lfloor R\,\frac{100}{100+F}\,\frac{e}{\lambda}\,(1+b/100)\,c\right\rfloor,1,99999\right) \end{aligned}
