I'm not super great with the star, but it's one of my favorites.
Your comment about speed sums up as SMOOTH is FAST. For me a uniform shooting "Pace" that has no misses is best for my score. Shoot it exactly the same way every time if all of the star is visible.
That being said, when I miss, it's at the bottom of the star.
The "Polish Plate Rack" is actually easier IF
you never miss.
It's fun too.
