Kounga hihi tino pai: he iti ake te wāhi arotahi, he pai ake ngā rārangi tapahi, he pai ake te mahi, he pai ake te kounga tukatuka; Tere tapahi teitei: he rite te mana CO, mīhini tapahi taiaho e 2 ngā wā; Pūmautanga teitei: ko te taiaho muka kawemai pai rawa atu o te ao, he pumau te mahi, ka taea e te roanga mahi o ngā wāhanga matua te eke ki te 100,000 hāora; He pai ake te huringa hiko-whatu: he tata ki te 30% te pai o te huringa whakaahua-hiko o te mīhini tapahi taiaho muka whatu, he C0, he 3 ngā wā teitei ake te mīhini tapahi taiaho, he penapena pūngao me te tiaki taiao; Ko te whakamahinga hiko o te mīhini katoa he 20-30% noa iho i tērā o te mīhini tapahi taiaho C0 rite. Pānga arataki mārama tino ngāwari: rahi iti, hanganga kiato, ngāwari ki te ngāwari ngā whakaritenga tukatuka.
