Not to get too deep in semantics, but the OP stated that it isn't unsafe to accelerate - not that it was unsafe to go slower. The first statement implying that he didn't consider it unsafe to accelerate and the second statement implying that one considers it inherently unsafe to go anything less than the particular speed. Not a big deal.
Anyway. Arguing safety isn't going to work unless you're in Texas, Utah, and possibly one other state. Washington is an "absolute speed limit" state, meaning that any speed that is greater than the posted speed is an offense. Therefore, it's not gonna help arguing if the speed was safe or otherwise.
You've redacted quite a bit of information and one thing that may help your case. My question to you is this: What has the officer listed in the Blocks "At Location Rf. Trafficway" and "M.P. Block #?"
