In this thread, and others, it backs up the idea of it being a "multi roll" table. Since the mobs have a high miss rate, the parry rate reported by APP is extremely low. This is because you can't parry a miss. But if you remove misses, it leads to numbers that seem pretty reasonable for fighting lower level mobs.
I don't know how much more testing you really need, to be honest. The poster on reddit was just starting his testing, but he posted enough data to draw conclusions from, which is really what matters.
