"to form a theory about due to the "LUCK" bar we had before. " That means: before 2.0. If you remember, we had a Luck Bar in the work window, like the current motivation and danger bar now. It was filled up to 24% for 1h and it got smaller together with motivation and it raised after equipping holiday set items. If you read my text carefully, I answer all of your questions... "There's no way to predict now what the chance drop rate is per xx amount of time, because there's no more luck bar. But I am going ahead and assuming it did not change, because for 1h jobs I get pretty much the same amount of drops."
