It doesn't seem a deal as big as some say this schedule thing is and I know it depends on the type of content and the "routine" the viewers of a channel are used to - but what about the sole fact that you're just starting with your science channel? To me as a beginner doing everything but the voice-over, a schedule seems a little daunting. I simplify the complexity of an animation if I'm in a rush and it's a defeating feeling but to imagine doing that to achieve the schedule of my YouTube channel with viewers expecting a video? Wow. If it really is important to have it I would make it work but what about just the first 3 months after you launch - how important it is than?
