I thought one of the internal fork washers had split and bent and sent pictures to Venom illustrating what I thought was a problem, and they seemed to agree with that assessment and sent me a new complete fork. The replacement fork was the same and i realized that's how it was supposed to be and they didn't seem to know any better than I. I felt kind of dumb after that but not too bad since they didn't seem to know any better than I.

Have you noticed any difference since changing the oil?

Those split washers are indeed part of the design of the fork. They are deflection washers, and it acts as part of the valving system. They are designed to resist moving until a certain pressure is met, and then deflect just enough to allow pressure to bleed off. A big part of modern fork tuning is adjusting that washer stack, both number, size, etc to change the pressure threshold.
