Ok, the theory behind this - I will update it every couple of months - I do about 50-100 routes a month so that should be sensible.
A route is entered if I have got up it in any style - i.e. from clean lead to hauled up by my partner. If I have been on the rock from bottom to top it goes in here. If I subsequently do the route in a different style then it will be re-entered again. Hence a second of a route will be in here, and when I subsequently lead it, it will be entered again. If I do the route in the same style as before (e.g. I lead the same route again clean, it still goes in but gets a "REP" in the grade column. There, Simple? It works for me:-)
