What criteria for running less than 36 lands (Casual EDH)?

36 lands seems to be the general baseline for what a commander deck should run, it’s typically how many I have in most of my decks as well.

What criteria does your deck have to meet to consider running less than 36 lands in your deck. I know cEDH has a lot of fast mana and is always less than that but in casual EDH do you look at average cmc? Commander cmc? How much ramp or draw you have? Etc.

Looking to see what the general public considers when deciding how many lands they include in their decks and if they do run less than 36 how does that perform?

Thanks!
