S-A3 contains suspension points that are excluded from the average:
SAG1,SAG2,SG1,SBG1,SBG2,SG2,SCG1,SCG2,SG3
Exclusions usually occur if suspension points are part of the stabilo but not attached to a dedicated stabilo
main line. In other cases they might be excluded due to their function as stabilizer in case of a large front collapse.
