I can already tell that the Forbes article is wrong - it used to be that it was based on your high 3, but for years now, it has been based on your high 5 years.  And it depends on how his compensation is currently broken out.  Retirement is based on your base pay.  And it doesn't matter if he has 51 years of service - his retirment compensation maxes out at 42 years of service.  

If you look at OPM.gov, and go to special pay rates it will explain it.  I doubt the $430,000 is his base pay, but includes incentive pay rates for people that are considered world class and extremely difficult to replace.
