And then, when you consider that trail conditions are not factored in - a trail with soft pine needles is equal to another trail featuring loose rocks in these calculations - the entire process is really just an estimate of which route is more difficult.Jeff Mhttps://www.blogger.com/profile/06623587270951440914noreply@blogger.comtag:blogger.com,1999:blog-3028206738007742119.post-82291643400255894772015-02-02T17:45:06.071-05:002015-02-02T17:45:06.071-05:00Your description of the formula for the difficulty...Your description of the formula for the difficulty factor is unclear. You claim it's the sum of square roots of two factors, but you neglect to mention more than a single factor. It looks like you have sqrt(2*elevation*distance), where I presume you're doing elevation in feet and distance in miles, which is a rather odd number, with units length.<br /><br />Do you mean for the formula to be sqrt( 2*elevation + distance), or perhaps sqrt(2*elevation) + sqrt(distance)? Those both have units of sqrt(length), which is again rather an odd unit to describe the difficulty.Joffrey Petershttps://www.blogger.com/profile/05673697679055743718noreply@blogger.comtag:blogger.com,1999:blog-3028206738007742119.post-56641928565403273912010-06-15T21:01:15.118-04:002010-06-15T21:01:15.118-04:00May the journey become the quest.
