Second, I'm hyper sensitive to what you are talking about and that SOB is stable and better be tough to get out at the end of the set up. Third, I check those legs regularly to be tight when I'm working with them, like once or twice a day. If the quick release seems a little too easy, then the leatherman comes out and it gets a tighten.
I haven't had a problem with it ever though.
For really strange set ups, like on concrete, I have been known to (A) set up the tripod with as many feet in the dirt as possible and (B) for those legs on the concrete, if I can't get it in an expansion joint, to chisel a hole (like you would use a star drill), with a 60d nail and get it so such a depth that it would really be difficult for it to come out. Takes about 5 minutes per hole but the metal spike fits snugly in the hole. Almost 100% of the time, I pick my setups such that I don't have that issue.
We recently did a topo where I had to have, at three points, at least one leg on a concrete sidewalk. Each one of the nails was set in the dirt and in a projection of the wooden expansion joint so that two legs were firmly in the clay and the other in a piece of wood. Makes a big difference.
The people who don't pay for it don't think like this though, unless you train them to think like this.
That is some good advice with the hole in the concrete, I am sure I will use that trick one day. I use the dual clamp heavy duty tripods.
Have you ever tried or used those Tripod floor guides? I never have, but if they work I may order a few of them.
