You use ISG when you need to count up, not down. But DSE saves a few bytes if you just want to execute a loop n times, and don't care what the value of the loop counter is. (Or if you specifically need it to be n, n-1, ..., 2, 1.)

So if the loop counter should go from 5 to 1, use 5 STO 00 ... DSE 00; and if the loop counter should go from 1 to 5, use 1.005 STO 00 ... ISG 00.
