Sure,
A modern square has a speed of 20 - 40 mph, it is capable of a good range in its glide, so is the reserve. Establish the depth of the spot either by a wind drift indicator or by calculation of drift in 2 minutes from opening against the ground and 2000' winds. Now run in crosswind at that depth of spot. The first group exit 500 metres short of the centreline of your DZ and groups follow at 5 -10 second intervals depending on size. Use gps for first spot and then modify as you go. If the local area demands a run in into wind, simply approach the run in at 70 degrees and intercept the run in about 500 metres short of the DZ. As you roll onto the run in, use a close in point and distance point on the horizon to aim for and in winds up to 20 knts give the cut as you cross the DZ. The first group will exit 5 secs later and then at 5 - 10 sec intervals - no problem! Give the last group some Schilling coins for the phonecall back to the DZ ! Don't worry about the turns, they are used to it and if not you can always hose out the back of a Van - I was used to 206's etc Private mail me with a contact and I will call you.
