I wanted to write my "new finding" on Multi-period Performance Attribution, but I found it's not new.
Check out AMC's answer above:
1. Rp - Rb = (1+Rp1) x(1+Rp2) - (1+Rb1) x(1+Rb2) is much easier !
where, Rp1=Ra1+Rb1; Rp2=Ra2+Rb2.
Schweser's version: R(A2)=Ra1*(1+Rb2)+Ra2*(1+Rp1)
In fact, R(A2) = Rp-Rb !!
