Me, too.
It's interesting that a reduction from 120k to 115k/year results in a 100% success over 30 years for both although an extremely higher average in the latter case.
I jigger around with FireCalc since I'll start semi-retirement next year and the DW will continue to work for 3-6 years. I'm sure there is a way to model this, but it is not obvious, since it doesn't seem to process multiple retirement years and incomes.
Longer years give better success at times, which is a bit disturbing about naive responses to FireCalc results, although it is reassuring.
