In terms of subs, it depends on a couple things:
1) Where are your views coming from?
2) How is your audience retention?
I ask those because it's possible that the people viewing your videos aren't the ones who would normally subscribe to that type of content. As for audience retention, if the 200+ people who are viewing each video are only watching a very small percentage of the video, it could be a sign that your content isn't good enough to capture people's attention, in which case you'd need to do some work on the videos themselves. That way your view to subscriber ratio can be higher.
Hope that helps!
