Can you roughly quantify it? Are we talking from million-to-one to million-to-one-point-five, or from million-to-one to hundred-to-one?

The announcement came as a surprise, so the update wasn't negligible. I probably wouldn't have gone as low as million-to-one before, but I might have been prepared to estimate a 99.9% chance that arithmetic is consistent. However, I'm not quite sure how much of this change is a Bayesian update and how much is the fact that I got a shock and thought about the issue a lot more carefully.
