Grind size adjustment with grammage

Here is a graph of the grind size adjustment for different grammages with the 46mm basket.

For this test I kept constants: 1:2 ratio, 9 bar and then aimed for 30s. If to fast a flow I went finer to adjust until I got 30s. I have kept the error range in there.

For comparison, at 10g, the grind size is similar to my IMS competition, 58mm.

Here the grind settings for 30s flow - left to right: 10g, 14g, 18g

And here the pucks - left to right: 22g, 18g, 14g, 10g
