As Connor pointed out in his comment on the last post, Incremental Statistics might still turn out to be a bit trickier than you thought once you start using them on many or very large tables, even once you’ve got the basics right.
Which is why there’s still a place for the detailed technical blog posts, once you’ve got the basics clear. The problem with not having the basics clear is that I’ve had people tell me things about Incremental Stats based on the blog posts and, when I read them, they make sense to me but I can also see why they might confuse others. Anyway, for completeness, here are some terrific posts about Incremental Stats.
Read blogs, by all means, but maybe start off with White Papers and the documentation and full presentations?
