Umuntu ovuzayo ukhulumile ukuthi ilensi inikezela ngesilinganiso esingu-2: 1 macro, kodwa akufanele sikhiphe isilinganiso esingu-1: 1 lapho siyisebenzisa ekugcineni kwayo okude kakhulu. Njengenjwayelo, yithathe ngohlamvu lukasawoti ngoba abukho ubufakazi bokusekela izimangalo, ngakho-ke kufanele ugweme noma yikuphi ukuphoxeka okukhulu.
