(c) For purposes of comparing the continuing pay of a supervisor whose position is under the General Schedule with the continuing pay of a subordinate whose position is not under the General Schedule, the following payments shall be included in determining the amount of continuing pay received by the supervisor:
(1) Basic pay, including a retained rate of pay under 5 U.S.C. 5363 and part 536 of this chapter or other similar authority:
