I don't think a schedule matters as much when you first start out. I would say though , the more content you upload early on, the more presence you give yourself , which you for sure need being new. If you have a huge channel is when the upload times become more important. If you upload every tuesday, your 1 million subs are gonna know you upload on tuesday and they are gonna be waiting for it. It you have 100 subs it's not really the same. I also think huge channels can get away with uploading less often because they know when they do release their video once a week, or 2 weeks or month, it's getting a million views. If you only have 100 subs you 100% know that will not happen so the more content you can put out to possibly get viewed the better. I'm not saying release 10 half assed videos a day, but I would for sure try and do more than 1 a week if you can manage it. Think about it like this. If you are a low viewed channel. You release a video on monday and it gets 10 views. You release another video the following monday , and it gets 10 views. If you had released a video, t,w,th,f,s,s, that would be 60 more hypothetical views you could have had that week and the following one.
