It is for adults Jake, I'd say you'd classify your pace according to how you compare with the rest of the kids in your age group.
This even extends to adult grades where someone could be fast or fast medium in their grade but actually only medium on the official scale. Otherwise you'd have no 'fast bowlers' in any comp except the very good ones.
