Hilarious that there's 500 comments on this, of all things.
You can safely say in a recipe book that caramelized onions take 10, 20, or 45 minutes or an hour. Chances are the writer has the best intentions and reasonable knowledge of the subject matter.
Nobody's going to sue you if you're wrong. So there's no single source of truth for how to caramelize onions. Life goes on.
FWIW, caramelization boggles scientists to this day. Last I heard/read, there are still unidentified sugars that occur there that don't occur elsewhere.
