It's always interesting to see particular datasets; when I have time I'll take a closer look, but one thing I want to reiterate is that the patch notes were misleading. The assumption that different stats affect auto-attack/shot damage or weaponskill damage individually has never been corroborated and casual observation in 1.20 continues to demonstrate that that assumption is wrong. Even in 1.19., PIE affected WS and auto-attack damage for LNCs. Since 1.19, ATK has always affected minimum, maximum, auto-attack, shot, and weaponskill damage for all physical DPS classes.
