If amplituhedron is so efficient in calculating probabilities why everyone is not using it

If amplituhedron is so efficient in calculating probabilities why everyone is not using it

Because, strictly speaking, the volume of the amplituhedron (https://arxiv.org/pdf/1312.2007) is applicable only to scattering amplitudes in $N = 4$ supersymmetric Yang-Mills QFT and just in a very specific limit. In particular, it is unsuitable for finding results in the $SU(3)\times SU(2)\times U(1)$ gauge theory underlying the Standard Model of modern particle physics.
