good post. ANY tank regulator gauge can be off by up to 10%. Those gauges aren't the most accurate.
For testing purposes, we used certified gauges, most of which are liquid filled. Thats the only way to get a true and accurate reading. TechT makes a nice digital gauge called the optimus. kinda expensive but does the trick. Great tool for pro shops and fields to test regs.
