RMDs are now reinvested, and tax brackets now follow inflation
Two changes to the conversion engine. Unneeded required minimum distributions are now taxed and reinvested instead of leaving the projection, and federal tax brackets now grow with inflation across the projection instead of standing still at today's values. Both make the reported advantage of converting smaller. Cases you built before today keep reinvestment switched off, but bracket indexing applies to them, so their numbers will read a little differently than when you last saw them.
