From the manual:

Insertion is implemented by inserting in the triangulation, then performing a
sequence of Delaunay flips. The number of flips is O(d) if the new vertex is
of degree d in the new triangulation. For points distributed uniformly at
random, insertion takes time O(1) on average.

I guess, for "usual" applications one would get a O(1) time, which is great.

Best,

Daniel
