True, but also not that good. All of the heat/cold/only on Tuesdays stuff should have been baked into the original experiment, really. Not that they should be able to take into account everything, but 60% replication does not indicate a very high standard. I mean it's not much better than if you just took and educated guess, with no data, since you could probably do better than 50/50. The whole point of the study is that it is supposed to be better than an educated guess.
