Grade sport climbs by breaking them down into small sections. Enter strings like "25 N 25 G V6", Ewbank or V-grades seperated by letters for the type of rest.
[ N = no rest, B = bad rest, M = medium rest, G = good rest ].

Calibration
To calibrate this to a particular crag or style think about two climbs of the same grade stacked on top of each other. Consider what the combined
grade would be with no rest (N) and also with a good rest (G).
Set N to be the no rest increase in grade, and G to be the good rest increase.
For example, by default N is 2.5, which means if you stack two 25s with no rest you get a 27.5 (a 27/28).
A good rest would add 1.75 grades and result in a hard 26.
