I'm not a Math person, I admit. But here are the stats for the recent 3 day giveaway of Angel Sometimes. Angel was free for three days, July 27th, 28th and 29th.
Somehow, I'm not sure how, Angel Sometimes always seems to be listed with these category/tag words:
Kindle Store > Kindle eBooks > Fiction > Genre Fiction > Mystery & Thrillers > Thrillers > Suspense
So…with those tag words, here are the stats:
About 2 p.m.: #73
About 6 p.m.: #43
About 10:30 p.m.: #36
About 5:30 p.m.: #25
About 7 p.m.: #22
About 8 p.m.: #21
About 7:30 a.m.: #17
About 1 p.m.: #18
As far as I can tell, it never made the Top 100 Free in Kindle Store.
Frankly, I'm not sure how important it is to know the stats. Interesting, though. One thing you can deduce from these stats is that I'm not real good at remembering to check them.
