Maybe the problem is not in number of pages with thin content (few sentences) versus other beefed up pages. Instead, maybe the problem is in what subject these thin pages are about and how many other sites write about the exact same subject these thin pages are covering.
Going back to pizza restaurants and comparing this to the imaginary site that lists cities in a country. Lets say that for each city it has only 2-3 sentences and you have many of these pages. I think a site that list cities would have greater chance to be hit by Panda as all this content is already covered many times over and over throughout the web.
I would also say that this is perhaps very different between ecom site and informational site, and further, that ecom site is more likely to be hit if the same products it is selling are sold widely by other sites.
Again, take a comparison between pizza restaurants site with one page per restaurant that has a couple of sentences and lets say, compare it with a site that is selling televisions, where each of a particular model of TV is widely sold on many other websites, and where page describing TV has also only 1-2 sentences. I think that in this case the TV site has bigger chance to be hit by Panda - especially as other sites will repeat pretty much THE SAME information, whereas there would be fewer sites on the web talking about this same pizza restaurant.
Think of this in the light of the following sentence from the same interview:
It is still not a good idea to repeat a ton of content over and over again. (...) The value add disappears.
So perhaps it is not how much you say - it is maybe whether it was said before and how many times and on how many other pages of your site and/or other sites.
With regards to the ratio to the other "beefed up" pages of the site - I am sure it is not so simple, it is also likely to be connected with the authority the site itself has on the subject it is covering.
