Good fonts (good vectors) don't include trash. Duplicated points is common error and this is a big issue especially for font designers.

When I expand my stroke some of points are duplicated. It usually happens on endings... If I move a dot we can find duplicate with same coordinates. Adobe Illustrator has same issue and that is the main reason why font designers avoid using it. It looks as you have same algorithm. I would recommend to pay a lot attention to this. I do love your app especially for pressure window It allows me to imitate calligraphy But now I need to clean path manually which is time consuming.
