Summary: This diff fixes an implementation error that was impacting slope and r^2 computations. It also includes optimization to the entropy warmup logic that should improve its performance with smaller/faster kernels. Further numerical stability optimization were brought in from the cross-pr on nvbench NVIDIA/nvbench#286 Since entropy tracks the frequency of appearence for each unique time element, the rounding precision applied on individual latency element can impact the characteristics of entropy convergence. This diff introduces logic to dynamically increase rounding precision to maintain a balance between entropy sensitivity and trend detection Reviewed By: xuzhao9 Differential Revision: D87379814
