I am wondering how conductors are counted for box fill calculations. In the illustration, the box on the left has 4 conductors, hot/neutral coming in and hot/neutral wires carrying power out to the next receptacle. In the box on the right, the wires are pigtailed, yet still two wires bringing power in and two carrying power out to the next thing downstream. But, there is also two short wires connected to the receptacle itself. Does this count as 6 conductors for box fill calculations?
