I am not at all the best person to get advice from for schedules because I have tried them and failed because I simply didn't have the time to keep to one because of school and other work I have, but if you do have the time the schedule option is definitely something good to use. Be sure to set it to be available at a time that will gain the biggest audience possible, so make sure you account for time zones, times when most people will be on Youtube (after school/work) etc. You could also spread them out rather than uploading them in bulk, especially if it a series that isn't really affected by time (for example a Lets play, something like a coverage for an event obviously wouldn't good to spread over weeks).
