Sorta correct - a few more variables than you make it sound, but its a plan. For starters, the $5k/yr $125,000 "double dip" theory isn't free. You do have to buy back the FERS time you missed to get retirement monies for it (currently at a rate of 3% mil earnings). It accrues interest if not paid back within 3 yrs/ - of course many already know you cannot collect a AD ret (7200 pnts) and combine that time with a FERS retirement - so, there is an ART (no pun intended) to maximizing the govt checks...but when done correctly, you can safely retire well above 6 figures. bcuziknow….;)
