Taking a standard P_{ED} of -0.8, Wolfram Alpha (which I affectionately call ‘Walfa’) kindly plots the graphs for me (click to view the Wolfram Alpha page):

It makes sense: asymptotes at the axes are a theoretical assumption. On the other hand it completely wrecks any assumptions about straight lines.

In other news, I’m away for the next week on a walking trip in Snowdonia which should be immensely good fun (and photographic).
