Hooked pulling front wheels then spun

Which direction does the shock get "softer" or "firmer"? Or does going to a different number make the bump stiffer and rebound softer? Or the other way around?

I'm dealing with a customer with a set of these. And no one can answer that question.

I agree, That's why I was looking for the instruction. I was going to buy a set at one time but never did. I just went to the website and got the instructions, It is confusing #1 is firmer, #9 is softer ? in both directions or in one direction.
