Everyone needs to do their own math, though. I run a network of news & information sites for business professionals in different industries and the numbers vary a bit, but are almost all much "worse" than your numbers. On utilitydive.com (covering the utility/energy industry) it's 35% IE and of that 40% is IE8. IE6 and IE7 are much less, but they also don't really work with our latest redesign so it's a bit hard to tell.
