From the player's animation events, BehaviorParam_PC and AtkParam_Pc. First hit: seconds at normal speed from the start of the move's animation (uncharged R2s start from a released charge, so they show —). Criticals include the weapon's critical multiplier. * The elemental motion value differs from the physical one shown; the damage uses each. "Own base": a projectile with its own base damage that scales with stats, not a share of attack rating.
