then while you are blindfolded your conditional probabilities for E+ should be Pr(E+|Heads) = 0.01 and Pr(E+|Tails) = 0.99.
The point is that there is a point in time at which the copies are subjectively indistinguishable. RPI then tells you to split your indexical credences equally among each copy. And this makes your anticipations (about what color you’ll see when the blindfold is lifted) depend on whether Heads or Tails is true, so when you see that you’re in a blue room you update towards Tails.
Sorry about that—didn’t catch it. I think this solution is probably right. I have a couple more minor objections scratching at the back of my mind, but I’m sure I’ll work them out.
