It could easily be done in Excel. It isn't live information but it still can be useful analyzing later on.
Just export the data. In a cell to the right of the data write AVERAGE=(C1,C2,C3,C4,C5,C6,C7,C8,C9,C10) noting that the center cell would be C5 or C6 so to get an average both ahead and behind. If the center was C10 then the average would ignore the future data and calculate only past data in the average. Or likewise if the center was C1 then the average would be just whats ahead, like a pre-emptive line.
Now the actual formula will be different but you should get the idea. Once you wrote the first line, drag the formula cell down to fill the rest. It should transpose the formula per location. Making an average spread easy.
If your good with Excel you can generate graphs and charts too. Well worth it for ultra fine tuning projects.
