Botched V-Dynos

Anyone that has used Virtual Dyno knows how sensitive this software is to errors, be it inputs or road conditions.

Here is a 3rd gear pull where I was forced to change lanes, still held the throttle wide open.

I recently ran logs up and down wind on a windy day, now I know my car has 6 hp more downwind than upwind.

How flat does a road have to be? I live in Louisiana so the roads are for the most part trash. I have a pretty flat and smooth back road by me that I use to practice my launches and I plan on using it to log for my tune. I mean it might have some waves in it but nothing that I can actually notice. When I drive super slow over it I can kind of notice some waves

Make two logs each direction on a still day and compare the four. If there is a grade affecting you it will be obvious.
