The announcement has aided sales, yep. We had (expectantly) slowed to 2-4 sales a day in the last week or so. However, since the announcement went up, it's jumped back to 10 or so in a day. Enough to see the quick rise in the ranks. But the higher it goes the harder it is to breakthrough. One of my novels reached #4 in the rankings last week, and was selling 100's a day, but couldn't breach the top three. Orders of magnitude. Still, any sale is a good sale, and 10 in a day is $20 in the coffers.
