Code of Federal Regulations Title 5. Administrative Personnel § 5.839.242 Do these rules apply to me if I had multiple errors?

You must be in the wrong retirement plan for at least 3 years of Federal service after December 31, 1986. You need not be in the same wrong retirement plan during the entire 3–year period. If you had more than one type of erroneous retirement coverage, then you will have a retirement plan election under these rules if one of the errors is of a type that qualifies you for an election.
