Maybe I'm dense but how is this different/better than the pressure gauge
that is already on the machine?

I gather that there is some pressure drop between where the machine gauge is
plumbed in and the brewhead - looks like around 1 bar of pressure drop. So
if you look at your machine gauge from now on and subtract 1 bar you'll
always have the approximate pressure at the head on your machine. No?

I wouldn't say that. Obtuse maybe, but certainly not dense.

The digital gauge is 'on the puck'. The dial is pre group and gicleur,
so _may_ vary some what over time.

I'm presuming the digital guage is more accurate and repeatable than
the dial. I wanted to obtain a resettable value with a high confidence
level.

The dial gauge is strictly a comfort factor and as long as the needle
is somewhere close, I'm happy. Taste is what determined the ultimate
setting. Now that I've got the OPV value, I've removed the digital
gauge and capped the adapter until the next inspiration.
