Have you P1, P2, P3 and P4, for your 100 W example, to clear

100w---50 ohm---+---1/2WL 291.5 ohm---50 ohm load

At '+', rho = 0.707, rho^2 = 0.5

P1 = Pfor1(1-rho^2) = 100w(0.5) = 50w

P2 = Pref2(rho^2) = 100w(0.5) = 50w

P3 = Pfor1(rho^2) = 100w(0.5) = 50w

P4 = Pref2(1-rho^2) = 100w(0.5) = 50w

Pref1 = P3 + P4 - 2*SQRT(P3*P4) = 0w

Pfor2 = P1 + P2 + 2*SQRT(P1*P2) = 200w

How's that?
