GLIDEANGLE 1 #1 January 30, 2015 McGraw’s Postulate The probability of jump-able weather for an individual on a weekend is: . . . . J/(DF) Where: J = Number of career jumps D = Number of days since last jump F = High temp on preceding Wednesday in degrees F. (Yes, at the extremes, this formula will result in invalid results such as dividing by zero or a probability >1.0. It is a joke.) The choices we make have consequences, for us & for others!

tred 0 #2 January 30, 2015 if I did it correctly I came up with about 13% seems low j=58 d=6 f=73 Quote Share this post Link to post Share on other sites

My basic rule is to not pass on any nice Saturday, so that I keep the D factor as low as possible.Instructor quote, “What's weird is that you're older than my dad!” Quote Share this post Link to post Share on other sites

Jim, also note that (number of jumps in past 30 days)/D is some type of happy factor number as well.Instructor quote, “What's weird is that you're older than my dad!” Quote Share this post Link to post Share on other sites
