The problem is that a lot of people having been using the claim that Scott is having trouble controlling the shift as an excuse to explain why he is such a pathetically weak Alpha, especially after such a HUGE deal was made about how special he is as a "True Alpha" (e.g. breaking Jennifer's mountain ash barrier). The writers seem to be backing this up via implication onscreen.

But then you end up with stupid and inexplicable scenarios, like Scott nearly shifting when mad at his father, but not being able to use Alpha-level strength when attacked by Berserkers. As with so much else about the show, there is no canon. Everything is fluid depending on the needs of the current scene.
