Sidee loo xalliyaa farqiga u dhexeeya gelinta iyo mitirka socodka ee isku xira iyada oo aan lahayn qiimaha S, Q ama qiimaha S, Q uu hooseeyo, sidee loo baaraa waxa sababa?

1) Xaqiiji in deegaanka goobta uu buuxinayo shuruudaha: dhererka qaybta tuubada oo ku filan oo toosan, dhexdhexaad cabbir buuxa oo la cabbiri karo, tiro badan oo xumbo ama walxo wasakh ah kuma jiraan dhuumaha.

2) Weydii macaamiisha in xuduudaha dhuumaha ay sax yihiin, in ay jiraan dahaadh iyo cabbiraad ku jira dhuumaha, in habka cabbiraadda si sax ah loo doortay, hubi in xuduudaha martida loo dejiyay si sax ah, haddii ay jiraan dahaadh, walxaha dahaarka waa la cabbiri karaa. Dareemaha dibadda ee xiran, hubi in derbiga dibadda ee dhuumaha la safeeyey oo wakiilka isku xidhka si siman oo ku filan loo mariyo;

3) Hubi in dareemaha si sax ah loo rakibay (Ku rakib dareemaha sida waafaqsan farqiga dareemaha ee ku xusan liiska M25) ee dareemaha ku-xidhan, hubi in dareemaha uu isku toosan yahay;

4) Hubi in fiilooyinka dareemaha ay wanaagsan yihiin, hubi liiska M91, fiiri saamiga gudbinta waqtiga, oo hagaaji rakibaadda dareemaha si ay uga dhigto inta u dhaxaysa 97%-103%;

5) Haddii saamiga gudbinta waqtiga uu yahay inta u dhaxaysa 97%-103%, laakiin qiimaha S iyo qiimaha Q ay wali hooseeyaan, taasoo muujinaysa in dhexroorka tuubooyinku uu weyn yahay ama dhumucda derbigu ay qaro weyn tahay, fadlan beddel habka rakibidda dareemayaasha Z;

6) Haddii saamiga gudbinta waqtiga aan la hagaajin karin inta u dhaxaysa 97%-103%, ama qiimaha S iyo qiimaha Q ay had iyo jeer yihiin 0, tallaabooyinka kor ku xusanna ay sax yihiin, waxaa laga yaabaa inay dhibaato ka timaado dareemaha ama martida, ka saar dareemaha oo isticmaal habka labada su'aalood ee kor ku xusan si aad u go'aamiso.
