Yes, the ones I made were accurate enough and even the periodic error was surprisingly small considering the pressure angle departure from the ideal (30 degrees instead of 20).
There is a rigid relationship between the PCD (Pitch Circular Diameter) and the number of teeth. If there is a departure from that, then there will be a hiccup somewhere along the circle where there is a pitch variation.
