Panyaya yekuchengetedzwa kwegiredhi, mazinga ekudzivirira akasarudzwa pamatanho ese anofanirwa kushandira pamwe kuti ive nechokwadi chekuti inodzivirira yekuvuza haipfuure chiitiko kana kukanganisa kwekudonha kana tsaona yekuvhundutsa yemagetsi yakaitika kumagumo; panguva imwe chete, zvinotarisirwa kuti kana muchengeti wepamusoro-soro akundikana, muchengeti wepamusoro-soro achaita kuti agadzirise muchengeti wepamusoro-pasi. Kukundikana netsaona. Kuitwa kwekuchengetedzwa kwegiredhi kunogonesa imwe neimwe yemagetsi emagetsi kuti ive neanopfuura maviri mazinga ekudzivirira kudonha matanho, ayo anongogadzira akachengeteka ekushanda mamiriro emidziyo yemagetsi pamagumo emitsara yese yegiredhi yemagetsi yakaderera, asi zvakare inopa akawanda akananga uye asina kunanga kusangana kwekuchengetedza munhu. Uyezve, inogona kuderedza chiyero chekudzima kwemagetsi kana chikanganiso chikaitika, uye zviri nyore kuwana nekutsvaga chikanganiso, icho chine mhedzisiro yakanaka pakuvandudza mwero wekuchengetedza magetsi kushandiswa, kuderedza tsaona yemagetsi, uye kuve nechokwadi chekuchengetedza kushanda.
