Yes, this is accurate! A good rule of thumb is that any time you move your camera or change your lens or framing, it's a new "shot" in the same scene.
Here's an example of a shot list I just did yesterday:
3 - Wide establishing of room
3A - Medium 2 shot of girls sitting at a computer
3B - Close Up of GIRL #1
3C - Close Up of GIRL #2
Insert - computer screen
As long as I am in scene 3, I will stay on the number three and change the letters when the shots change. Once the scene changes (new location or new time) I will then start over with the number 4.
4 - WIDE of the street
4A- medium tracking shot of Girl #2 walking down the sidewalk.
4B - Tracking Close Up of girl's face.
The shotlist usually informs what goes on the slate!
