PR(A)=PR(C)*0.85+0.15-(1)

PR(B)=[PR(A)/2]*0.85+0.15-(2)

PR(C)=[PR(A)/2+PR(B)]*0.85+0.15-(3)


Let  PR(A)=1 帶入
則
     PR(C)=1
     PR(B)=0.575帶入-(3)
    PR(C)=1.06375 帶入-(1)

    PR(A)=1.0541875帶入-(2)
    PR(B)=0.5980帶入-(3)
    PR(C)=1.1063帶入-(1)

    PR(A)=1.090帶入-(2)
    PR(B)=0.6134帶入-(3)
    PR(C)=1.134 帶入-(1)

    ....重複下可得更加精確的數值

. 由以上趨勢可看出PR(C)>PR(A)>PR(B)
