Ndudu zotayidwa-: Mbali yaikulu ya mtundu umenewu wa e{1}}ndudu n'chakuti imatha kutaya, kutanthauza kuti siyichacha ndipo makatiriji sangathe kusinthidwa. Ili ndi mapangidwe osavuta, palibe zoletsa chingwe, ndipo palibe chifukwa chodera nkhawa za kusinthidwa kwa makatiriji, kotero ndiyosavuta kugwiritsa ntchito. Panthawi imodzimodziyo, chifukwa cha mapangidwe otsekedwa kwathunthu, amachepetsa zolephera zomwe zingatheke chifukwa chogwiritsa ntchito mobwerezabwereza ndi kulipiritsa. Kuphatikiza apo, kuchuluka kwa madzi a ndudu zotayidwa-nthawi zambiri kumakhala kokulirapo, komwe kumatha kukwanitsa-nthawi yayitali, komanso kuchuluka kwa nkhungu kumakhala kokulirapo, ndipo kugwiritsa ntchito kwake kumakhala kowona.
