Yes, this is true. Hopefully if using the Fixed Amort. Method the person has some extra savings on the side to supplement income when needed.
I guess the problem I see with using the RMD method is when you are trying to control your income for ACA premium credits.
Totally agree, holding off on starting the SEPP until I have a better idea of my income in ER and see how the first couple years shake out (so far inflation is pretty gnarly). Really though, if my portfolio grows quickly enough I'll be happy to bust the MAGI and will worry instead about BTD!
