Its worth noting that comparing bubbles per second from one setup to another is almost worthless due to the amount of variables involved in this stuff. The amount of gas in a bubble can vary depending on the working pressure of the system as well as tubing sizes, etc. I'm sure the orifice in the bubble counter itself could play a role here as well as potentially atmospheric pressure, ambient temperature might have an effect, the depth in the tank where you have your diffuser, and probably even more factors past that.
