Thanks for your reply Stefan ! I can understand that.
Every year we have our steering committee meeting to finalise one CU which has no or less issues reported . After that we upgrade almost 35 to 40 farms ( Test/QA/PROD) . Before finalising one CU , we used to refer all technet articles blogs to see what all issues reported from other customers . Your blog is one of the references where we can get lot of other customers feedback. Thanks for the blog and update.
