Did some research and as it turns out, first thing in the morning is the best time to upload a video for smaller channels and for channels with millions of subs, it really don't matter when. Theory is, the evening hours in the U.S. is when 90% of uploading occurs so when we upload videos in the evening they instantly get buried with thousands and thousands of other newly uploaded vids. By uploading a video in the morning or early afternoon we are not competing with thousands & thousands & thousands of other uploads, just thousands...lol
