To get any info worthwhile from barriers, one would have to delve a lot deeper into such things as the class of horse, the quality of jockey , as well as the horses running style just to name a few. Most average punters assume that if there is a large enough sample, that each barrier would get an equal distribution of runners of all styles, jockey capabilities, and favouritism. This may well be the case but I haven't seen any info that detailed as yet and I dont think I'm likely to. Like most other factors in racing, there would be millions of different combinations for each.
