      That's a well made video and an interesting mod. I'm not really sure the best way to measure your pressure on this machine properly sorry. I had a Gaggia Classic and I set the OPV on that to 10bar static using a portafilter gauge, but the Classic has a 3-way solenoid. Your machine doesn't have a 3-way so the dynamics are different and the relationship between OPV pressure and group head pressure will be different. I see you've posted this on the Gaggia forum too. I'd say they'll be interested to see what you've done and you're more likely to get an answer there, just be patient.

        I agree...

        Without access to a Pressure Gauge Group Handle, setting to 10Bar static pressure will be very close to 9Bar while drawing a shot...

        Mal.
