Rear HRC/LRC Blocks for a 22 "Anti Squat"

[501x_NewUser]

Hi, sorry if this is already mentioned else where. I also know this is a dumb question that I should know, but I don't and want to make sure before I mess it up

I am looking at some 22 setups and I see the Anti Squat listed in the setup sheets for the Rear of the buggy.

Does this anti squat degree, mean the degree of the spacer under the HRC block + the degree of the piece that goes inside the HRC block? I notice that both have listed degrees on them. Or does this mean if I want 2.5 degrees anti squat I would have to use the 2.5 degree one in both cases so they match up? or does that add up to 5 degrees?

Anyway any help on this would be appreciated. Thanks ahead of time.
