I ask the question because I have already done four different drive sessions. And so far when I look at the values in my map for the cell that I have hit they read .93 for the most of the cells. The first time I had about .96-.94 and I did the copy with lables and paste mutip with lables and see the graph on the main ve change. I up load the new file and when I go driving around for the next three times I am not really seeing any improvement in my values. They all still read .93 exept for the higher kpa values they read about 1.05. I am I headed in the write directions or should I have seen some sort of improvement. I know the auto ve pdf say you want your values to be 1.00 + or - .01. It seem as if my value needs to go in the other direction I am just not sure. Thanks for any help.
