I'm going to guess that the weather there is somewhat like Michigan. Dreary much of the time, with severe fluctuations in seasons.
It performs pretty well here, but probably not as good as it would in places that don't experience overcast weather. My old stone, which was a serenity coated enhanced RB moissy, showed a bit of green here, but my Amora OEC has no green, which was verified by Erica at JbEG (who had it on a dark day in Washington State).
