Excuse the bump, but I feel the need to bring this back up for two reasons.
One is that Patriot Day had recently passed and The Star Spangled Banner's writing's anniversary is any day now.
The other is that I had estimated the slopes for the stars off tangent measurements. So I decided to redo the stars to be more perfect.Starting with a circle of the same measurements as before, I inscribed a pentagram, deleting parts of the circle where needed, then deleting the whole circle and lines inside the star when finished, just like before.
What is different, however, is that unlike before, where I estimated slopes from what the tangent of the angles were, this time I went line by line, stud by stud, using the table of a graphing calculator with the following formula used: Tan(angle)×X+1.
The result was a more perfect star:

You can see it in Badspot's Block Party amongst the crowd of other builds.
Compared with this, the star currently on the flag:

Superimposed, here is the difference:

I will be taking some time to replace the previous stars with the new, more improved ones.
