Those numbers are pretty accurate. We (7mesh) don't list the ratings as we actually have never been able to get them from Gore-Tex (officially). Gore believes the ratings don't reflect real world usage (and anything over 10,000 is considered waterproof so 30,000 doesn't make it 3x as waterproof). Their focus is on durability of waterproofness, not just out-of-the-box - so they don't like the lab game where everyone uses a test that gives them a nice number, but it often doesn't hold up in the real world of rain/snow/dirt/oil/contaminants etc.
This is a good resource regarding waterproof fabrics - [http://www.paddypallin.com.au/blog/all-about-waterproof-fabrics/](http://www.paddypallin.com.au/blog/all-about-waterproof-fabrics/)
