But more important, as the race progresses, the likelihood of any particular horse winning changes. In general, we'd observe (or possibly assign) different probabilities for different horses depending on their varying positions as the race progressed. But my main point is that when any probability is not 100% as the race progresses, as in the 30/70% scenario for some quantum system, it makes no sense to say a horse, or quantum system, is IN that particular state. You can still affirm the MWI under this scenario, but it would be much more logical than metastasizing worlds without end. We can still have odd universes, but what you're claiming is beyond the pale IMO.
