So today when I went down an ab line, and applied area was to the left, I was matching up and everything was fine
When apllied area was to the right, agopen was following the line in the program just 1-4cm from the line, yet it was showing a gap on screen (painted area) and in the field work of 20-30cm.
Tried shifting antenna postion in agopengps and all sorts.
Am I missing something simple, or do I need to recreate field etc.
