The "store bought" ones I have are aluminum and basically the upward pressure created by tightening the ratchet strap wedges them in between the ground and the frame keeps them in place so no notches needed. I occasionally check them to make sure they stay tight if they settle/shift any and give the ratchet a click or two if needed.
I would assume these homemade ones would work the same way. The only improvement I could see that might help some is to create a base that pivots on the end of the legs, or at the very least, place a few squares of treated plywood on the ground under the legs so if in softer soil/sand, there is a larger footing than just the end of the 2x4.
