Hooked pulling front wheels then spun

This might be a dumb question but did you bleed the shocks before you put them on ?
I also found this chart I thought I had one but couldn't find it,
The Calvert's are 1 is firmest and 9 is softest, seems backwards to me.

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.
