That's the beauty of the V3i, you can adjust it for your soil and type of hunting. It maybe also that you need to tweak some things on that program to fit your needs. Sometimes just lowering the RX and starting at the bottom and moving it up until you find a smooth place to run it. I have had times in my soil when i could run it at 14 and at other times about 10. I learned to just keep it at 11 unless i have to lower it. That program likes Indian Heads and Wheats for me anyway. Good luck getting it set up.
