Waihangahia tētahi putanga matatini ake o tēnei rerenga He iti ake te ātete hau o tētahi kōpae taumaha ake i tētahi kōpae māmā ake, nā te mea ko te kaha e hiahiatia ana hei whakatere i te kōpae e ōrite ana ki te papatipu o te kōpae.
Ko te tikanga, he putanga matatini ake o te rerenga ko "He kōpae taimaha ake ka iti ake te ātete hau i te kōpae māmā ake engari na te kaha e hiahiatia ana hei whakatere i te kōpae e tika ana ki te papatipu o te kōpae ka heke te whakatere o te kōpae, me te whakaaro he pumau tonu te kaha o te kaupapa.
