[Y]ou should be as ready to drop it to 69% as raising it to 71%.

No, you should be as ready to drop it to 69% as raise it to ~70.98%. With rounding, obviously, the above isn't numerically wrong, but that's not my objection: it encourages the reader to think of probability updates in percentages as addative, which is wrong.

(edited: fixed my wrong numbers...)
