Other models' hours don't mean shit, sorry. Depends on so many factors. You have to consider type of show, target demographic, whales you may get, their schedules, sports schedules... Biggest thing is find a time that works for you when you're at your best and stick to a schedule. Your followers can't find you if you're not sticking to a rough schedule. I cam either after lunch or after 10pm my time for my schedule. They know when to find me. Sometimes I add to the times if I need to make more.
Every model could tell you a different time works for them vs someone else. Find what works for you. This is trial and error. If you go on when you're naturally awake and at your peppiest, tends to work better for you.
