Just done it but found a number of questions difficult to understand.
e.g. Q18 - No idea what you are looking for! It is 1500 to get Gold. So I have to fly enough to get 1500 points. Now how much I would be willing to fly? Well if I could do it in as few flights as possible that would be great, but that is highly dependent in what comes up at work and what I happen to do on a personal basis each year. Or you asking whether I would want to hit Gold for less flights? Of course, wouldn't anyone?
