yes, they are allowed to claim 2%, 1.75% or 1.5% for those years of service, up to 10 years total. This does not get anyone on FERS close to even 80% of their final high 3. The best gig in the federal government is still CSRS with LEO's. They can retire early with 2% for every year and no penalty for early retirement after 50. Plus, LEO's have a special payscale that provides UP TO 25% more money in salary than the regular GS scale. Not far behind the CSRS LEO gig is the special FIRREA agencies payscale (25 - 30% above the regular GS scale), better benefits (e.g. FDIC has a 10% match on 401K contributions and most of these agencies have subsidized health care and free dental/vision and life insurance). So a GS-14 equivalent at one of these agencies can make more than the SecDef.
Bottom line, you can't make more than 80% of your high 3 in federal service except for extremely rare circumstances. The law says "up to 80%" in everything that is published.
