Louver facade (Thinkparametric)

Greetings!

Recently I found Tutorial with interesting subject. Louver facade openings were established through attractors. However, complete tutorial was made completely chaotic. They were making it completely unprepared. During the tutorial tutors were changing their mind about how to do certain stuff. In order to make it work they spent last 15 minutes of tutorial correcting the scrpit. Because I was working different shape I could achieve the wanted effect. Even when I tried to create it from the begining while setting up everything right (using the corrections they have made at the end of tutorial) I have got even worse geometry. Was this tutorial already a discussion subject or is there discussion with a subject similar to this?

Thanks in advance
