Over the past week or two there has been some people suggesting that Google does not review manually every single reconsideration request.
A new Google Webmaster Help thread has one such complaint but the truth is, at least from what we are told, Google employees reviews 100% of all reconsideration requests.
I have been told that directly by Googlers and Matt Cutts did a video a couple years ago on the topic. That was before Google swapped the reconsideration requests in the manual action viewer where now all reconsideration requests have to be submitted via the manual action section and thus all are reviewed by humans.
They might have some templated responses they use but humans do click on, read and paste the response.
Here is Matt's video:
