In the late 1970s the EPA published a table showing the effect of an 18-mph wind as a tailwind,crosswind,and tailwind.
I've meant to post it.I do think the data is in the seminars though.
SAE criteria for coastdown tests limit crosswind testing to fairly low windspeed because of the difficulty of reducing the data.
If memory serves me,if any run has a standard deviation of 2 % or greater ( and crosswind will effect this ),that data must be discarded.They're very stringent.
Dead flat course and zero wind is almost absolutely necessary when you see the mathematics necessary to compensate for more than one variable.
If you've got no plans for the rest of your life,then I'd say go for it.
