So, I guess that Bas does it in another way than you. OTOH, your condition seems quite intutive to me, but it was stated: " the cap-recap sequence must have same material gain " > >> >>When you restrict these to material wins, it seems to me that you are thinking >>of avoiding traps ? > >He doesn't.
