The main premise of pinky pie is that you save a few moves compared to ULUR, and you avoid the awful dots case.
However, you lose a lot of time due to the fact that you also have to recognize centers, along with edges in the method.
Saving only a few moves does not seem worth it with the recognition that comes with it, as well as the shear number of algorithms.
I would say pinky pie is, at best, slightly worse than ULUR, and at best, is only slightly better in the rare chance that you get a skip.
