If element has multiple mistakes it can get -5 according to the recommendations, so with Bradie jump called as UR in the system, judges may easily go to -5 in GOE with it, cause it already had bad timing (which is very important for a combo), bad take off and the landing. If a skater planned a triple and did a double, it is judged as a jump with a mistake basically. And double jumps as single elements are rarely looking that good to get high GOE, because they don't have height and distance as triple jumps for example (unless its a double with delayed rotation).
