How accurate is the pressure gauge on the GS3 MP ?
i assume its reading from the group head and that would mean accurate to .5 Bar ?
thanks!

Wouldn't the gauage itself determine the accuracy? Not sure it's reading from?

Fwiw it's setup to read the pressure on the puck, so as far as I know you shouldn't need to do any kind of offset in your head, however I'm considering renting a scace for funsies soon anyway.

I checked my machine with my Scace when it arrived, the group top gauge was spot on. With the Linea and other machines, the capillary tube is upstream of the group usually on the cold side of the boiler. The GS3MP is is right above the group. The last place you can take a measurement before the water hits the puck and is directly attached. No capillary tube.

How close (or spot on?) was the coffee boiler offset value?
