Tape A is used every odd-numbered day for 16 days. Tape B is used on days 2, 6, 10, and 14. Tape C is used on days 4 and 12. Tape D is used on days 8 and 16. This allows Tape A to be overwritten every other day, while Tapes B is overwritten every four days and Tapes C and D are overwritten every 8 days.
