Repeat at 16, 11, 8, 5.6 seconds, and at 4 seconds the whole sheet should be illuminated, and at 0 seconds turn enlarger light off.

I don't know how much simpler it can get? What's the source of confusion?

Aha! Now I know what you are doing. You are counting backwards from the total exposure time and uncovering the paper at certain points. I thought we were talking about progressively covering the previously exposed strip, not uncovering unexposed paper.

I'll pm for some more clarification.
