Did it, it is how I tested my Sky panel. You can se the plot on my website, go to tech tips then Sky melody review page.. I drove between two known elevations, one at Harris Hill glider port down to the Elmira regional airport. Accuracy was within three feet I added the 10 as a modest gesture. The car was cold to start then warmed as I drove, the unit still reported accurate readings. You can see the temperature plot as well. Keep in mind on my computer the graph can be zoomed in on to pinpoint data. John
