Hmm, bit of a funny one this. I passed with 648 and a guy at my tests got called straight back with an amazing 845. Another guy got invited the following month with 658 (v. close to my score), so I figured I would be around the top of the list. But that was in January. 845 guy passed and is now in Lux, and there are people on his course who were reserves with similar scores to mine , who got called back and passed the second stage (obviously).
In other words, I don't really have a clue. Sorry.
