Gentoo and Fedora should be switched. Poor over people are always snobs demanding perfect grinds, perfect water temperature, and perfect pour overs. Espresso users are the same but I like espresso and fedora lol
Pour overs are very forgiving and will give a decent result if your new or just eyeballing measurements but also if you want it exactly like you like it you'll use a scale.
Fedora IMO is pretty forgiving and if I want my Fedora install exactly how I like, I'll follow the same steps as always when configuring and setting up.
