Yes it is a tough trick. But it isn't hopeless. I found I could get pretty tight baseline runs by running two directions(nulls wind), constant ave. speed via Scangauge, hills become insignificant if the baseline and change are done back-to-back, and driver variability "smooths" out if the course is long, say 10 miles or more.

Takes lots of time and fuel, unfortunately.

A cruise control would help maintain the constant ave. speed, but unfortunately that doesn't work very well on the MT Insight
