What is an idiom for better than "textbook case", "by the book" or "best practices" [closed]

Something indicating above and beyond the standard best practices, superior to by-the-book-experience.

For instance, I would like to use it in a blog title The non-textbook / non-standard / beyond best practices / virality of XYZ, to indicate that XYZ is doing a better job and not following standard textbook techniques.

The following does not indicate more effective or positive. "The non-standard approach to organic discovery and viral loops in XYZ"

Alternatively, I'd like to say XYZ does not follow the best practices of virality but it doing way better. An idiom, phrase or even a word would work.

Is anything wrong with saying it's doing it in a unorthodox yet superior way?
