See below pictures showing two different scales. I guess 1/2 inch scale comes naturally to me and then I tried the 1/4inch scale. With more practice looks like I might be able to get better at 1/4inch scale.
I didn't try the 1inch scale due to two reasons, first wasn't sure with my machine without any special accessories if I will be able to do 1inch stippling. So stayed away from it.
Here are the pictures:
