[Shop-talk] Corrugated fiberglass panels. How many screws?

I am putting corrugated fiberglass panels up as a cover over a deck. I bought the thickest white ones my local Menard's carries. The finished roof will be about 17 x 8 feet. This is a simple shed-style roof, with water draining down the corrugations at a 16-degree angle to a (wavy) drip edge.
Each panel is 8 feet long, and covers 2 feet wide when overlapped one wavelength. I have corrugated strips of wood which purport to match the shape of the fiberglass. The concept is that one drills a hole through the top of the wave and put a pole-barn screw (with built-in rubber washer) through the top of the wave, through the corrugated strip and into the wood crosspiece below. I have four such crosspieces.
My question is: How many screws do I need across each panel?
If I put them three across, that would be a dozen screws through each panel (the overlap section would mean that two panels share the four screws on the edge). Is this enough?
BTW, I don't intend to cut any of these panels. The panel length should be correct, and I will make the width come out correct by overlapping more than one wavelength.
