Obviously circuit orbiting should be an initial turn away from the runway, which flies in the face of this,
...which makes it so highly dangerous and to be avoided at all costs. If baulked in the circuit, the safest procedure (and standard at several airfields) is to continue to fly the circuit at circuit height/altitude until able to have sufficient spacing to approach and land. Next best, but only when it's quiet, is to 'extend downwind' but doing this when there is following traffic means that you wind up with a trail of aircraft behind you, inevitably one will see an opportunity to short-circuit (pun intended) and cut everyone else up.
