I have no idea where the stock is that they're planning on sending me. If the question is "what carrier service do I feel best about based on my anecdotes?", I am better than Amazon. If the question is "based on all the places from which Amazon could fulfill my order [or combinations of outstanding orders], which one(s) are likely to satisfy the constraints given our large base of actual carrier performance, and which one of those is optimal?", it seems laughable that I'd have any hope of answering that better than Amazon.
(I oversee Logistics software for another e-commerce player. Our network is vastly simpler than Amazon's and yet I'm quite sure we're better at it than our 99.5th percentile customer.)
