Pure sttrike rates for each barrier wont tell you much on their own. You have to take into account the number of horses in each race as well. For example barrier 15 at track x may have a very poor s/r as against barrier 1, however the horses from barrier 15 will have at least 14 others aginst it whereas horses from barrier 1 may only have another 3 or 4 in some races. So the average number of horses in a race will average about 10, whereas in races where barrier 15 is involved may average 16 or 17 therefore producing an incorrect bias. The inside barriers will still come out better overall but not as significant as what some people think.
