In lots of places throughout blender, such as physics uses arbitrary values that mean absolutely nothing, and make it an almost impossible to get to the correct value without a lot of trial and error. For example the stiffness settings for cloth (10000 for tension, and 50 for damping tension).
I think it would be far more understandable if something is either fully tense (value 1), or not tense at all (value 0).
Also other things need looking at such as the wind strength, it seems to have unlimited strength, whereas it would make much more sense and make it far more intuitive if this value were in scene units (mph, kph)
