You were asking about best way to get back on schedule. You are at 1:30/1:30 and want to get back to 8/8. That is a difference of 6.5 hours. The easiest way is probably to shoot 1:30 one afternoon, then again 8:00 the next AM. Pretend you had done a partial fur shot. You had asked about doing it more gradually, which you could. It just disrupts more cycles instead of just one. The only requirement is that you don't do cycles sooner than 12 hours apart. You could absolutely do 16 hours apart followed by a cycle with 14.5 hours apart. Whatever is easiest for you.
