as many others have said, you're probably pretty average on these forums. I just think that many people are like me and don't post alot about their savings rate when they're high income - because it's damn easy to save 50-60% of your income when your household income is north of $300K.
As far as definitions of what lean, median and fat fire are, that's up to you. I can't fathom living on $20K a year any more than I think I need $200K (the old conventional 'wisdom' of how you need 70% of pre-retirement income).
I'm the money manager in our household, DH is the spender, although he has scaled back huge as the prize of early retirement gets closer. I've been tracking our spending over the last 5 years, so I have a very good idea of what we 'need' to maintain our current lifestyle, and that's our target retirement budget plus $15K as a buffer (travel, buy toys, 'shit happens'). We could scale back in down years (hello 2020), or splurge in other years. I have 3 retirement numbers, my 'lean' fire that keeps the lights on and food in my belly, my 'status quo' number that let's us live the way we are now, and my 'fat' number that would have us travelling and spending more.
and I do think the tone of the forum has changed over the years, it used to be very hard core, lean fire and all about the face punches. I like the more tempered vibe.
