Hi Pilou,

> So with a good training, a good tempo, I can make around 30 seconds!

Hey, it's not definite until you prove it! :)

You can't claim 30 seconds unless you can do it in 30 seconds, until then you can only claim 45 seconds!!!! :)

Using a circle and boolean merge (instead of drawing an arc and using difference) I removed a few picks from the MoI solution - new world record in MoI = 34 seconds! (video below).

Also my system is kind of sluggish when running the screen capture, I would probably be able to go faster without the capturing on...
