I am pretty much doing the same. My "background" just has me as a habit creating spreadsheets and tracking changes/outcomes. In some ways I just can't help it.
At the end of the day, I want to first grow my income to account for a growth in "spending/inflation", while second at a minimum maintaining (hopefully growing) my after-spending withdrawal overall portfolio value.
I've achieved the first to an extent, but so far not the second, primarily because I've had some additional spending beyond my plan so far.
