From an engineering point of view, I suspect that if you load a 'plane up to twice its weight, to simulate 2G, then the MLG would be fully compressed. Any further loading beyond that will result in the shock going straight into the airframe, as the shock absorbers are beyond their working range.
Also because the CofG is in front of the MLG, the landing impact will cause the front of the aircraft to drop (lessening the G in the cockpit area.) and cause the rear of the plane to rise, increasing the G forces on the tail. All this rather begs the question of where do you put the Accelerometer to record the forces, or maybe use several of them and take the highest reading.
I think for certification reasons all aerobatic airplanes must have both a 5 point seat harness, and a recording G meter. This will have moving needles for +ve and -ve G, and is fitted into the instrument panel.
