I checked your section and it was almost identical to what I got despite the fact I used 61 points. You can get variation with the number of points but not so much if the section has gentle curves.
I used smooth finish. I can get what you got by using painted fabric.
Check a NACA0012. It should be around 0.009.
The Javafoil data I got aligns well with the old NACA report I referenced earlier.
