In Response To: Rollout: Double from the bar? (Timothy Chow)

Sorry, I posted the second rollout twice and inadvertently omitted the rollout with no Jacoby rule. Below is the rollout without Jacoby. I said this was a "marginal" double; maybe 0.050 is more than marginal but the point is that Jacoby makes a significant difference.
