As you continue, it will get better without much, if any effort on your part. Don’t over think it, just keep shaving and all will be revealed. Don’t worry about BBS as it will happen from time to time. My first pass always gives a very acceptable shave but I do two because I enjoy it. Five minutes is not enough “enjoy” time. Sounds like you are doing very well just keep at it and your enjoyment will grow along with your skill.
