Not specific to Goodwood,What I am basically doing here is thinking about it as a standard overhead join, here you would let down on the dead side of the circuit and THEN come over the upwind end of the runway as described - nothing new or specific to Goodwood about it, just a standard join, but as you are already on the dead side coming from the south you can let down before you reach the airfield and join straight on the crosswind section. You are inside all the houses so no noise problem.
Also you might like to note that most of the runways have turns for noise after Take off
Just one other point, circuit height at Goodwood is 1,200'.
See you there sometime.
