I love scheduling videos. I'll edit a batch and schedule for a week or two in advance, it's been working well for me so far. I also state in my videos the upload schedule briefly so new viewers know when to expect that type of content again.
Being consistent is the key rather you have a schedule or not. I tried to have one but I prefer to upload whenever I see fit. Which is very often but no set times or days. Having a schedule takes away alot of the fun for me. Makes it feel more like an annoying job. Making myself do a video when I really don't feel like it.
