I'll add a bit in addition to this. Considering that SE would not want the environment to affect the crafting rate that much, if it is there, having a group of people, who are not logging their data, and are less that 1000people, confirm that moon phase affects crafting, does not provide sufficient evidence that moon phase and other environmental effects affect crafting rates.

Humans have inherent logical fallacies, which is why all scientific correlations are done using numbers. Using only flawed anecdotal evidence, you can end up with the situation of rain dances (which is exactly why rain dances occured). We now know that rain is a product of shifting atmospheric temperatures causing condensation, but ancient tribes used human observation to come to the flawed conclusion that rain came due to their tribal dances.

Thus, crafting may be affected by the weather and moon, but there is no way to confirm that without the effort of ALOT of people, like more than your linkshell, and even then there is a chance to be wrong.
