and I ask visual studio or script editor because in VS I would use GH_Transform which needs to multiply in the opposite way of Rhinocommon. GH components use GH_Transform so actually if you want to get these partial results to transform in the same order as GH you need to change the order of transforms first unless you use GH_Transform.
Mathematically, RhinoCommon matrices multiply in the correct way. Intuitively, Grasshopper transforms multiply in the correct way. If you want to first move, then scale, the order for a compound transform is (1) move (2) scale. To achieve the same with RhinoCommon transforms you need
scale * move.
