To me, it seems very elaborate and expensive for setting/checking CG. And, it would typically only be used once per aircraft (or after repair). Fine tune adjustments for CG from there is based on flight performance and personal feel and not a static test.

If we take a position that such a device is critical in knowing the precise CG, then the foam that contacts the leading edge surface allows for too much variation from point to point which will drive a higher tolerance range which is not productive for precision. More effort would be required to ensure the plane is set in the CG saddle exactly the same way every time by anyone that used it.

I don't see a benefit of this CG Stand over the more simplistic Great Planes or other device capable of showing a rough CG location from the leading edge surface. Perhaps someone may see it a bit different.

Only my opinion, I could be wrong.
