Shop unit of grease volume: one complete pull of the gun lever. Output varies widely between guns, commonly around 1 to 1.5 grams but sometimes double that, so serious programs calibrate each gun by weighing ten strokes and label it in grams per shot. Bearing relubrication amounts calculated in grams are then converted into shots on the route sheet.
Calc says 6 grams, with this gun that's four shots, not a dozen.
