That's similar performance to NASA's Gipsy solver and a couple other PPP solutions.
The practical problem is PPP falls apart when there's any sort of multipath or noise, with will be the case for any receiver not in a completely open field. A single nearby tree is often the difference between 4cm accuracy and a meter.
