Well, look at that nice Gaussian distribution! Well, except for those that have actually reported more than 100%! I'd be interested to know if that's just a age thing, as BTDretire reports, or perhaps lucky investments, inheritances, whatever.
I wonder how this would differ amongst the non-mustachian crowd. Perhaps I'll post this in another forum I frequent and share results between the two at a later time. I think the crowd there is a bit older though - so it might not be a good correlation.
As far as "rules" for calculations if anyone else wants to contribute. I purposely tried to not make too many rules. I didn't want to spend weeks figuring out our lifetime savings rate, I just wanted to get in the ballpark - I'm hoping you don't spend too much time thinking about this either. It's just a bit of fun.
