A routine states the heaviest thing in it rather than a single per-application number, because the products in it are used on different days and in a set order. That order is under “How to use” below.

The whole routine for fine and thin hair, and every item in it is weight 1 or under. No oil, no butter, no leave-in mask — nothing in this box can put your hair flat, which is the only thing that actually matters when hair is fine.
Wash with CL-01, condition from the ears down with CN-01, SR-01 on the mid-lengths while damp, ST-01 before any hot tool. That is the entire routine, and there is not a fifth step missing.
