Thought I would share my experience dialing in the Feldgrind to match the Lido 3. I was using the Lido 3 at 10.5 for chemex using a metal filter from Able Brewing. I ended up at +3 full turns from 0 on the Feldgrind for the same grind visually and the same flow rate. I calculate this as a 4X since there are 14 marks per full turn on the Feldgrind for a total of 42 (10.5 x 4 = 42). Hopefully, the ratio holds up for Aeropress.
