Polartec v Schoeller v Windstopper article?

I have not seen any direct comparisons, though I'd imagine someone on this site has the information.

Here is what I have:

You might also want to scan this:

The chart on page 8 is not truly quantative, but it does give a rough comparison similar what Beyond Clothing does with its own rating system.
Subjectively, I have found Schoeller Dryskin to be about 70% windproof, highly breathable, a faster drying than Powershield or any of the Windstoppers I have used. Powershield is very slightly less windproof than Windstopper, has fantastic stretch, and can take a long time to dry. Breathability is poor compared to Dryskin. Windstopper is windproof, but breathes worse than Powershield.

Edit: I was trying to find Patagonia's "What Percent of Naked" article.

It discusses Windstopper, etc.
