I am good actually. I had a 600psi / 40 bar gauge at work that I was able to get to fit, barely, with a bunch or different adapter fittings to the portafilter. It was reading roughly 13 bar, and I am pretty sure I am down to about 9 +/- .5 bars. I imagine this is why, for the longest time, no matter how fine I ground the coffee, I would still get a reasonable flow out of it.
