In Jan-March he made the most, which was post video. In the past few months, he's been making less than 350, which is the most current and furthest from the video.
But then you'd expect to see the effect in the immediate aftermath, not over 2 months after the video was uploaded. Also, you would expect a huge uptick in $, then a slow decline, Chris kept growing at a somewhat-steady rate.
This reminds me of something Ethan Ralph said, he said that he managed to get his momentum back after getting out of prison by immediately settling into a routine, that's the most important part of any sequential work, be it comics, podcasts..etc, it has to come out consistently on-time, and Chris fucked it up.
It also speaks to how small Chris' fandom is and how disliked he is amongst Internet culture. Chris only got less than 1,000 dollars per month regularly on Patreon not including Mr. Cherry. Pewdie got 5,000,000 views for making videos featuring Chris. That's 5,000,000 new potential Patreon customers and ebay buyers. Chris should have been rich by now.
It's well known that most people will not pay for online content, you can, at very best, get like %3-5, that's why almost all web content providers/service start-ups that target consumers have a free version, because if they don't, nobody will even try them.
RedLetterMedia for example has 839,085 subs on YouTube, but they only have 6,311 patrons. Now consider that we're talking about a very high quality content creator here, and you will see what I mean.
