Black box insurance - how long before you see stats?

[McPhersonator]

The cheapest insurance I could find was RAC Black Box insurance. I consider myself a safe and efficient driver so I was happy with this. I'm just wondering, how far do you have to drive before you're given a score? I keep looking at the RAC telematics site and it just says, 'Your score will be calculated after you have driven a sufficient distance.' I've done at least 150 miles since the box was installed. I am going to do Lancashire to Kent and back over Christmas, so I'm sure that'll give the site something to show! But I want to know now. What can I say? I'm a gamer, I like getting high scores.
