Euclidean distance degree conjecture for point resectioning varieties

For a generic configuration of nn points, let RnN,h\mathcal{R}^{N,h}_n denote the corresponding point resectioning variety, and let EDD\mathrm{EDD} denote its Euclidean distance degree. Resectioning EDD conjecture. EDD(RnN,h)\mathrm{EDD}(\mathcal{R}^{N,h}_n) equals a degree-NN polynomial in nn for all nN+2+Nhn\ge N+2+\left\lfloor\frac{N}{h}\right\rfloor. This extends the expected eventual polynomial behavior of Euclidean distance degrees for resectioning varieties; the preceding discussion notes that computational experiments suggest a degree much lower than the initially expected degree Nh+N+hNh+N+h, but gives no resolution beyond the conjecture.
