Wow that's unbelievable. My first thoughts are that weight drop doesn't compensate for what must be a steep rise in class to drop that much in weight. Also, if a horse drops from 57 say in a c1 to 52 in the city, he is dropping 5kg sure, however he is on the limit and the handicapper may have wanted to drop him more but could not. A few of the horses in that sample no doubt would have been the type you see down the bottom in listed races and WFA races, you know they're outclassed, but they can't be given less weight.
