I understand your motivation and what you're conveying as a better solution (I think), but if you're truly talking about tap density (as in transverse axial pressure measurements), I don't believe that the micron resolution of measurement is necessary for the context of preparing espresso, IN MY HUMBLE OPINION.
It's not like we're packaging a paralytic like succinylcholine for intravenous use which requires a resolution less than 0.1 mg.
Or, am I missing something? (and I don't mean that sarcastically)
