Weird energy consumption oddity.

I am just reporting what PlugShare shows in the elevation graph. Using PlugShare Desk Top https://www.plugshare.com/ (not the phone app) I clicked on "Plan new trip" in the main menu on the left about half way down. Then entered the starting point as "Orlando" And the destination as "Lakeland" This will give a rout between the two. On the right hand side there is an elevation button. I clicked on that to show the elevation graph. The lowest point on the graph is 85 ft the highest point on the graph is 229 ft. It shows the starting point in Orlando as being ~100 ft. It show the highest point as being 229 about 2 miles from Lakeland and then dropping off to 190 feet.

 

Download the (free) Google Earth Pro for Win10 or MacOS, which will give you more detail than you know what to do with , especially on a big monitor.
Once you have put a "from" to "to" in the Search box, you can right-click on the created route line for the elevation profile. If you want to narrow your search, you can zoom in, then right-click on any yellow balloon or red dot for "Directions from here" and "Directions to here" choice - choose a new pair of points.
The Elevation profile gives you total elevation gain / loss, which is the most useful data for comparison. Start and End points only, don't tell you whether you are on a "rail track" or a "switchback" kind of road.
The Kona dash data is very sensitive to slope change, especially on shorter routes. Even a cloverleaf elevation can make a difference...

 

I stand corrected. Obviously your trip plan is more accurate than my generic one.
