If two weeks is the longest stretch, I don't think anyone can assert the rep is "earned."
You're referring to a stretch of only 50 plate appearances. If you're basing a rep off 50 PAs, you are grasping. No one earns a rep over 50 PAs. His career 800 PAs with a .768 OPS is far more telling than a cherry-picked, subset of 50 PAs from two years ago.
