In Response To: Cube error rates (Matt Cohn-Geier)

Regarding the first position, yes, not doubling in this and all the repeated situations does cost more than not doubling in this situation and reconsidering after fan/fan. The latter cost is what the bot reports, and if it is 0.05, the former cost is approx. 0.062. The difference here is not large, because an exact repeat of the position only happens with a probability of 256/1296. In the typical 'static situation', the effect may be much larger.

If you reach this position, you will usually get dinged for 0.05 in total, but on a very bad day you can be dinged for something like 0.5. Those occasional high dings are needed for unbiased feedback, because the typical 0.05 ding is too small. The average ding is just right. On the other hand I can see why it is regarded as unfair that you can be dinged 0.05 or 0.5 for the same error.

Douglas Zare discusses this in his GV article "Unbiased Nonsense" and proposes a variance reduction method on the error rate. I don't think that that would be accepted by the bg community, but it is an interesting concept.
