Avoid docking on one grip and then trying to fly yourself to the other grip. This places more loads on the formation. Be extra aware of where your neighbors are if you are docking near compressed radials. The compressed radials tend to squish together the slots in your part of the formation. That means less room for the same number of people.
Hoops tend to build with a bulge to the outside.
This will expand the radials in your section of the formation and help the base get back to its proper shape. If you are docking in a place where the radials are expanded, then you will probably have to go deeper into your slot than expected, especially if you are in a hoop. The expanded space has to be filled by the same number of people, so the people have to be closer to the centerpoint. If you are the closer of a hoop and the space is wider than your wing span, then motion to your neighbors to come deeper into their slots. A legs out signal works wonders in this situation.
