I don't think there is such a thing as a Standard join these days. Try joining overhead when there is parachuting going on and you might be in for a surprise. Try joining overhead where there is a MATZ above and Typhoons flying around and you might get a surprise.
At airfields like this I favour a base leg or straight in join. At airfields with a SOHJ when I am arriving from the dead side I'd join on crosswind over the upwind numbers.
At "home" I like to join overhead just for fun, and see how accurately and quickly I can crank it around, lose 1000' before crossing the numbers. Our circuit is quite tight due to noise abatement so I think final is typically 0.2 - 0.4 nm.
However if joining from a straight in or Base then I'd be prepared to give way to anyone in the circuit. I shudder to think of someone on base having to "go around" to someone on final as this doesn't really do anything to increase separation. Better would be to extend downwind if there is any ambiguity before turning base, or for the person on long final to adjust speed etc., or go around.
What annoys me more is incorrect position reports...Someone calls up "on final" when in actual fact they are 6 miles out. I had that at Bembridge one time, I was downwind for the westerly runway and someone called in final. I decided to extend downwind and I was half way to shoreham before they passed me !
