Not sure about that, the "P" in R.A.P.T.O.R. stands for patternless. Seems if they have a pattern they are really not a R.A.P.T.O.R. Just my 2 cts. worth.
The Aptor, "Patternless", or "Patternless Stripes" can vary a great deal. Some start out with some pattern, sometimes it will fade-out, sometimes it will not. Some are more like Stripes, some are more like Reverse Stripes, but for the most part the ones with pattern, it will be broken, dotted, and dashed, etc.
