This is an excellent point, but I think you mean that when taking non-1 words into account it would show that Google is about 1.5X underrepresented. If indeed that is the case, then the true "search/discovery" market share is about 90%, as supported through other commenters' site data.
Also compelling is the data AJ007 presents on number of days/month used. Bing at 8.9 trailing Google(21.5) and Yahoo (18) significantly. To me this clearly suggests that Bing users are the relatively unsavvy searcher of the Bing/Yahoo bunch. Does anyone have any recent demo data on the search engines? My guess is that Bing has a relatively older mix.
