Facebook data does not match (excel and FQL)
Building a facebook analytics app. I get daily new morals as follows:
$start_time = $timestamp = strtotime('2012-01-30');
$end_time = $timestamp = strtotime('2012-02-27');
$fanadds = $facebook->api('/**************/insights/page_fan_adds?since='.$start_time.'&until='.$end_time);
When I compare these results with the data of the exported Excel sheet, the numbers don't match.
Comparison:

Does anyone have an idea why this is?

I just saw https://developers.facebook.com/bugs/204643062967390 , one of the comments there says that page_fan_adds can count the same user multiple times if they like, as opposed to and over again
It looks like this might be the reason - Insights documentation lists page_fan_adds and page_fan_adds_unique separately; implying that page_fan_adds will have duplicates
