We can draw some interesting conclusions from these sims:

1) R7 does a pretty good job after all with mediocre pens. The problem is that nobody should play with pens smaller than 4.5/6
2) K-O is still better than Hi-Lo
3) D-R7 still outperforms R7 by more than 4%
4) Note that K-O with good pen and good spread can do better than D-R7.

Hope you enjoy the sims!

Sincerely,
Cac
