I could argue that's correct but I wouldn't agree that necessarily has anything to do with the "class" of the race, e.g. black type cf. R65. It has to do with the relative performance of horses in one race cf. the next. It's the same type of error to suggest that because it is a black type race, it is a better "class" race than a non-black type one. You need to judge that by the performance of the horse in any given race, not by the title of the race or its status.
