A website for an avante-garde electronic musican may have almost words at all -- just icons that play music. If that musician has a relatively uncomon name and a loyal fan following with websites linking to the musician's, two words may be enough to get a top ten listing.
So the important question is "top ten for what?" -- but check this site's posting charter as you may not be able to answer that.
Two sites I do in the same competitive sector use two different styles: one uses concise, basic info pages (1pp) and the other uses longer more in depth info pages (2pp). Both have pages that rank in Google top 3, sometimes concise site comes above the more in-depth site, other times its the other way around.
On another site I have quite long (3-14pp) comprehensive article pages, which are long 'cos scholars often want to print them. These also rank v. well. All 3 sites are PR5/6. So I'd advocate designing to give your users what they want.
YMMV...
IMHO it's important to have copy that flows, and a goal, rather than achieving a specific word density. Most of my pages follow a structure like: title, description paras, feature lists, call to action, and related page links. Then again, I've found simple parts lists pages can also work well for part number search results. I personally don't think there is a magic formula.
