How much air into Townshend 3-D Seismic Sink

How much air should be pumped into a Townshend 3-D Seismic Sink? Should there be a certain number of lbs which can be checked with an air guage?

The 3D that I had did not. Regarding inflation, I was advised by the importer as follows: "Just inflate the Sink so that there is no more than about 3/16 inch between the bottom lip of the top section of the Sink and the bottom of the bottom section, and all will be fine."
