Here is my 120 Short Sums Chart. It contains no Doubles ofcourse and thats why it only hits 72% of the time. Write down the hits each day in  column form with the locations of where the hits came from...by number and letter. I promise this will give you many good hits...but you must write them down each day. Start 30 or 60 days back and come forward in your state.  You will see !  

 example: 

            013  A1 section..w1 Horizontal line ...H 1  Sum 4 

                     013 A1, s1, h1, sum 4
