I am also very dubious of using the RoF rules to handle many projectiles vs. many targets in an area of effect. They were designed for shotgun blasts and machine-gun bursts against individual targets. Instead, I would start with empirical data or back-of-the-envelope calculations about hit changes at various distances down the cone, and pick numbers such that chances to hit are in the right ballpark.
