Grade IV - Requires a very long day
Grade V - Requires an overnight stay on the route
Grade VI - Requires a few days
Grade VII - Expedition
So seing that boulder problems are on average 6 moves long and it takes you about a second a move we are talking then 6 second problems. I don't think it is relative to this scale.
The above explanation of the commitment scale is actually not really accurate. Today I was looking at the ice climbing in the rockies book. My friend had suggested we do Slipstream sometime this week. He had never heard of it and just saw a couple of pictures on a conditions site. Well lets just say the pictures were taken at the easier part of the climb. The technical rating of this climb is not inhuman @ WI4+ but the commitment is Grade VI. According to the scale above that means it takes a few days. Wrong for this climb. It is graded that way because there is a huge serac (hanging wall of ice which is part of the glacier) which hangs over your head for most of the climb therefore posing a danger which you have no control over. Another reason for the grade is that the route is a km long. Take Waterfall wall and climb it over 40 times that's how long this is.
Check it out for yourself. Its the route that is on the left hand side to the left of the butress/arete. Oh and by the way, supposedly someone soloed it in 2 hours. Cwazy schfuckers
