I don't even think that's true.
Because a Proc at high level procs three times in a row just like Acceleration.
So if your opening cast procs, you have 3 in a row. Then at that point if the next cast after that doesn't proc, the you can hit Acceleration... or it might just proc again so you've got another 3 procs coming.
This is why I said what I did.
I understand trying to "force" stabilize it per se the way Rongway is talking about... but that still doesn't change how fast or slow you're going to end up in your melee combos, because they are completely unpredictable.
Which in my opinion is why RDM DPS has such a huge disparity between high and low damage. The Rotation just does not follow a set pattern because of the way the Job and Procs work.
