Shawn: Formula tweaked, found it! Currently showing 27 sales for the best seller 9 instead of 11 for the timeframe you provided). Secondarily, there is no way to understand returns using SalesRank, so it’s a necessary evil.

Shawn:
Can you provide the link or name of the best selling Kindle book so I can take a look? Or email me (you have the address).

It looks like the Kindle formula may not quite be completely fixed yet. Instead of tabulating too few books now, it seems to be tabulating too many.

On our top selling book so far this month, NovelRank shows us selling 11, where Amazon only shows us selling 8. That’s only 3 units difference, but then there have only been 3 days in the month so far.

Our second best selling title shows 5 units sold so far on NovelRank, and 5 units sold on Amazon, so that is correct.

The next best selling book shows 2 units sold on NovelRank, and 2 units have been sold on Amazon, but one was returned. This will probably not get subtracted in the NovelRank count at all, if past experience is any indication.

Not complaining in the least, just giving you more info to work with, as you continue to refine the process. ;0)

NovelRank checks every hour, from 2 minutes to 25 minutes past the hour as it goes through every book. There have been no lapses. The only possibility is Amazon’s API did not return a change, while the website did. Can’t adjust for that. If you had a specific example, email me (address in FAQ) and I can check logs.

Have the improvements affected how frequently NovelRank pulls data from Amazon for non-Kindle (i.e., paper) books? I’ve noticed over the past three or four days that Amazon sometimes goes through one or two hourly updates before NovelRank “catches up”. For example, NovelRank might show the 5:00 PM data point, and then not show a new one until 8:00 PM, despite updates visible on Amazon’s page at 6:00 PM and 7:00 PM.

Thanks for this great service!
