Rectification wrt. a non-regular polytope is meant to be the singular instance of truncations on all vertices at such a depth that the hyperplane intersections on the former edges will coincide (provided such a choice exists). Within the specific case of pip as a pre-image these intersection points might differ on its 2 edge types. Therefore pip cannot be rectified (within this stronger sense). Nonetheless the Conway operator of ambification (chosing the former edge centers generally) clearly is applicable. This would result in 2 different edge sizes in the outcome polyhedron. That one here is scaled such so that the smaller one becomes unity. Then the longer edge will have size c = f/q.

All q = sqrt(2) edges, provided in the below description, only qualify as pseudo edges wrt. the full polyhedron.
