So, first, it's written very well, but the first point should be that league tables won't change behaviour as that's the contrary. Then talk about how it would promote and push surgeons to be better and have a better record rather than competition between surgeons. The grammar is good and the points about data on surgeons that can be used to quantify them, just be sure to structure your arguments more or less in the order that the suggestions appear in. Hope this helped (and made sense) good luck on Wednesday!!!
