>> 0.5 on a single hole is quite high. One of my clarinets scores 0.3 for the upper joint (only cork) and 1.0 for the lower (cork and fish skin). My MAG is from JL Smith. Are the units different? <<

Mine is not from Smith but that doesn't matter. A small difference in the way it's set up can change how much force is needed to seal against the pressure.

My specific measurements are for comparison with themsevles, not so much with other mag machine tests. I could turn the machine up or down and get a different measurement using the same pad and amount of force.

>> Please explain. The other pad types went to zero when you pressed harder? Some leakage is desirable? <<

I tested a few pads and materials, leather, bladder, cork, synthetic and more than one model of each pad material. All pads other than the kangaroo leather pad got to 0 with approx "normal" amount of force. They varied slightly with amount of force needed, probably because of levelness and/or firmness of the pad/material, but none required pressing very hard to get to 0.

Using the same "normal" force, the kangaroo leather pad got to 0.5 and then remained there no matter how much harder I pressed. This showed that it leaked through the leather itself.
