Greetings! I have been creating tutorials on how to use Apple devices and Software for over 15 years. When recording a tutorial I still try to envision that I am sitting next to someone showing them the subject of the lesson in person. I want to speak clearly and not too fast. When recording lessons I never narrate the lesson as I record it. I always record the audio track first and then record my screen or screens while I listen to that audio. For me, this is the best way to get the correct pace and timing for the lesson.
