the % grade is, I believe, measured as 100Xvertical drop divided by
horizontal travel ( i.e., it's the tangent of the grade angle), expressed
as a percentage. It could just as well have been slope travel rather than
horizontal travel, but I've never heard of anyone doing it that way, i.e.,
the sine of the slope angle, as a %.
