IMHO it should also be not just a company procedure, but set in stone for all operators in that area, Then there can be no Commercial advantage to any operator and if you swap companies the SOP's are identical. As an aside, if there are several of you in the same area, you know the wind direction you can build up your own mental picture of exactly where everybody is and what they will be doing, instead of one crew making a split ##se turn on to a short final and another setting them selves up in one of the afore mentioned approaches.
