TBA, It's really a choice between the last 2.

Read my update notes which try to explain the difference between coarse and fine.

P.S. Sorry I have not had much time to play with this further as my daugfhter has been sick. I think this file has potential to adjust a few more things, but I just have not had the time. I may get back to it soon, I don't know. But don't be afraid to experiment on your own.
