Gabor is the guy behind SEprofiler/nakedportafilter.com and the one who mods shit for Hoffmeme like this vintage lever and the moka pots.

>how does he measure the weight?
I'd assume by pouring it into a cup on a scale after brewing. Hence why it happens at ~48 seconds after the pressure has sputtered out.
>how do i read this
10 seconds~6.8bar
28 seconds~8.79 bar
It not technically hitting 9 bar is probably just the location of where he modded in the profiler.
>and would that mean the brew pressure is between 6 and 8 1/2 bar?
It means its a slow ramp up to about 9 bar, then the pressure drops off as the puck degrades and liquid flows through it. From the quick start of that pressure it looks like he preboiled the reservoir, then screwed on the top.
>pressure meaningfully change with a different grind size?
Yeah. Its either going to piss out quicker and hit a lower peak, or clog and hit 9 bar sooner then choke. Its not like a lever or something else with pressure control where you could back off a bit when that pressure hits a "wall". Your only control is turning down the heat or pulling it off the flame.
