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.
Part 1 - Default options - GLOBAL AND PARTITION Part 2 - Estimated Global Stats Part 3 - Stats Aggregation Problems I Part 4 - Stats Aggregation Problems II Part 5 - Minimal Stats Aggregation Part 6a - COPY_TABLE_STATS - Intro Part 6b - COPY_TABLE_STATS - Mistakes Part 6c - COPY_TABLE_STATS - Bugs and Patches Part 6d - COPY_TABLE_STATS - A Light-bulb Moment Part 6e - COPY_TABLE_STATS - Bug 10268597

For the avoidance of any doubt, all views expressed here are my own and not those of past or current employers, clients, friends, Oracle Corporation, my Mum or, indeed, Flatcat. If you want to sue someone, I suggest you pick on Tigger, but I hope you have a good lawyer. Frankly, I doubt any of the former agree with my views or would want to be associated with them in any way.
