I enter all my numbers into FireCalc. I get a 100% success rate, so from there I start increasing my "annual withdrawals" by $1000. I continue to get 100% success rate for the 1st several increases of $1000, but then on the next increase my success rate drops to 0%. Nothing in between.
This last $1000 increase is about a 0.6% increase from the previous amount entered that gave me 100% succes rate.
