Stars crossed!

I commute. I have time to do this stuff.
Under the stars crossed, the percentages are presented and plotted in the photo.

So what do you need to hit?

Needed to hit value along with the percent to hit under stars crossed and not:

4: SC: 80.1% 2D6: 91.7%

5: SC: 64.4% 2D6: 83.3%

6: SC: 47.7% 2D6: 72.2%

7: SC: 31.9% 2D6: 58.3%

8: SC: 19.4% 2D6: 41.7%

So, Mat 6 against 12 drops from 72-48% pretty sweet.
