Hi everyone. Nice video jamminjamy!
I'm also a new owner of a Baratza Encore. My setting for the French press is exactly 30 to begin with, and adjust depending on the beans.
I don't have a Hario V60 but the Baratza site says start with 14 and adjust from there.
As for your flat bottom auto drip, is it an electric dripper or a manual pour over one? Do you have a link so we could see the type and filter that you use? Filter thickness plays a big part in your grind size.
For a pour over one, you might want to start at 20 and adjust from there. I saw someone use between 19-22 depending on the beans. I use #18 for a 150ml and #20 for a 300 ml on a 3 hole wedge type dripper.
If it's an electric auto-drip. I don't have a good answer for that, generally, you'd want to go finer on that as the water tends to pass through the grounds faster.
