The dps of this and the Trailblazer are multiplied by the number of targets struck by the arc, I'm sure of it. Every time an arc occurs, all targets affected in the chain are hit again. If one shot arcs to three targets, all are hit three times, dealing triple the damage normally done.

This explains why hordes get cut down quicker than individual zombies, and also why there's a lot of lag generated when using a Gigavolt on a large horde. Thus, aside from augmenting deadly and overclocked, piercing can increase dps done to all targets simply by shooting into a bigger group.
