Metaanalytically, I suppose I would be least likely to burn down the dorm (or merely set off the smoke detectors) tomorrow, rather then tonight, for tomorrow’s action depends on a success tonight, and 2 vs. 3 candles seems insignificant compared to familiarity with the action. Although for determining the night most likely to burn down the dorm (or etc.) the additional candles would probably be most crucial, and accumulated carelessness from the evidently 7 arson-free nights could balance any initial inexperience.

I suppose it would indeed take a miracle to light 8 candles for 8 days.

[And it's not worth risking a mandatory Arson/Pyromania Awareness "floor program". Can't we go see a movie or go bowling or have psychological testing done on us like normal floors?]
