Ok here is a question for you, can you input the numbers like this:
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
0.5, 0.5, 0.0, 0.5, 0.5, 0.5, 0.5, 0.5
that way it will be more accurate for games with smaller units (like mine)
