Efficiency = how much air is consumed per shot, literally. Bottle size has nothing to do with this metric. Obviously, a larger bottle will allow you to shoot more paint, but that doesn't make the marker "more efficient", just as having a larger gas tank doesn't make a car more fuel efficient.
@@BigTaffy1 A gun being an air hog and a user not getting enough shots from their marker because they choose to use a 48/3000 tank are two entirely different things. I hope this makes sense. In this video's case: 80ci x 4500 psi = 360,000 J (total possible energy held within the bottle) 1792 shots from a bit less than 360,000 J (the bottle was not fully consumed, so call it 95% consumption rate = 344,000). 344,000/1792 = 192J/shot. You can also characterize it in ci/shot, which is about 23.5 in this case. As you can hopefully understand, the marker itself determines the volume of air used per shot, which is entirely independent of the tank. Use the car analogy - the car determines how much fuel is consumed per combustion cycle. The gas tank size just determines the total amount of fuel that can be carried. Total fuel carried and consumption rate are two entirely different things that combine to define how far you can ultimately drive. Very simple stuff.
