Related, I see that the interpolation used is Akima interpolation. I guess this is:

Is there a particular reason for this choice?
The references in OP use Lagrange polynomial interpolation degree 4.

I think I observed overshooting in other interpolations methods and thus chose Akima's method because it is fully local. But I do not remember it clearly. I am testing against the source method: https://github.com/JuliaAstro/EarthOrientation.jl/blob/master/test/runtests.jl#L18
