7/10 is hardly a brilliant score for the best in the world is it.
In fact on most ratings 4-7 would mark the average range.
10th best in the world is a dismal 4.6/10 - so the 10th best got less than 50%.
2.9 for LTN and STN is not great, but only 1.7 away from being in the top 10. Statistics like this are pretty worthless.
