    A 1.8%pa degradation over 10 years would be, 83.39%.

    Linearising it to make it “more intuitive” I guess.

    But 2%pa degradation gets you very close to the 18% over 10 years figure. 1.9649% to be more precise.

    Over 20 years you are down to ~67% and ~55% at 30 years.

      And upcoming EPA regs will require the 80%, 10 year claim. I think that starts for MY28? Not 100% confident on the timing
