  • We are comparing Valving Logic r-zeta with restackor zetaC.  Valving Logic zeta doesn't take into account the full lev ratio as does zetaC.
    • CONCLUSION:  zetaC is always less than VDB r-zeta.

  • We can assume there is a minimum amount of reb force needed at 2ips, depending on the application.
  • And there is a bare minimum needed for any application.
  • The restackor zetaC plot was used to design new targets with r-zeta ranging from .59 to .70 at 40ips.
    • r-zeta at 2-5ips varies depending on ls reb target parameters.
  • Tips on matching r-zeta to ro wogas on press target tab.
    • Assume reb to be linear*.  Match reb force at 40ips, then see where 2 & 5ips falls.  [the same way we have always looked at c force]
    • Use zeta correction factor to align 40ips.
      • * 1 stage reb is fairly linear,
      •   2 stage with 28.10 sep has approx 10 lb dip at 5-10ips
