Based on your questioning, I think you'll get along just fine here. To answer the question in the title of the thread, no, the experiment is far from over. Look how long Nick Blackburn got before he was taken off the 40 man. Vance had 2 solid seasons in the majors and struck out more guys than Blackie ever did. Clearly something isn't right here, so he's going to get as many chances as he has options to prove it.
