Imithetho yobukhulu benkundla yebhola
Nansi i-quirk ethakazelisa ngempela yegeyimu. Izinkundla zebhola akumele zilingane nje kuphela kodwa, empeleni, zingaphathana kabi ngoba imithetho isho ubuncane nobukhulu bobubanzi nobude kunezilinganiso ezithile okufanele zilandelwe.
Uma kukhulunywa ngobude benkundla kufanele ibe phakathi kwamamitha ayi-100 noma amamitha angama-90, futhi ingabi ngaphezu kwamayadi ayi-130, noma amamitha ayi-120. Ububanzi abucacile ngendlela efanayo ekucacisweni kwayo. I-pitch ingaba ubuncane bamayadi angama-50, noma amamitha angama-45, ububanzi futhi ifinyelele kumayadi ayi-100, noma amamitha angama-90.
Yebo enye yezinto mayelana nenkundla yebhola ukuthi kumele igcine i-aspect ratio, okusho ukuthi awusoze wayibona inkundla engamamitha angu-90 by 90 metres. Lokhu kungase kulingane nobuncane nobukhulu bosayizi kodwa bekungeke kugcine isilinganiso silungile ukuze singavunyelwa.
Kukhona nobubanzi obuhlukile bosayizi kuye ngeqembu lobudala iphimbo elisetshenziswa ngalo. Abangaphansi kweminyaka engu-8, isibonelo, bangadlala ku-pitch esukela ku-27.45 metres kuya ku-45.75 metres ubude futhi isuka ku-18.30 metres kuya ku-27.45 metres ububanzi. Iqembu leminyaka engaphansi kwe-13 - Under14, okwamanje linebanga lamamitha angama-72.80 kuya kumamitha angama-91 ubude namamitha angama-45.50 kuya kumamitha angama-56 ububanzi.
Yize kungekho ukucaciswa okuqondile kobukhulu izinkundla okufanele zihambisane nazo, kunosayizi wenkundla ophakanyisiwe ukuze amakilabhu asebenze ngawo. Emaqenjini aphezulu angamamitha angama-64.01 ububanzi ngobude obungamamitha ayi-100.58.
