From outside the valley bubble, your raises sound fine to me. Tons of people would think it totally crazy to expect sustained 8% raises year after year during recessions. And you don't cite any other reason you want to quit. I wouldn't over-interpret the numbers. There are so many other reasons you might be paid a smaller raise on a given year, it's no good to overload your interpretation of this. You need, not a justification for giving you a lower raise, but just specific feedback on whether your performance is adequate and what you could improve. If the money seems fair to you and you are treated reasonably otherwise, it shouldn't matter that much about the number fluctuations, once you have clarified your anxiety about performance.
