I just look up everything fresh, now. There have been so many changes from before, during, and after covid-19, the two SECURE Acts, the Social Security moving targets. Heck, just last week I tried to update my own RMD year/age and needed to research that one, since it has changed/is changing over the next few years. I put the date and values table into my Excel sheet years ago, and did the "2 SS, file and suspend, delay until 70" analysis, and now, nothing there applies.
