Saxnaanta cabbirka ee mitirrada socodka cufka kulaylka waxaa saameeya arrimo kala duwan, oo ay ku jiraan qaabka qalabka, nooca dareeraha, heerka socodka, iyo xaaladaha rakibaadda. Caadiyan, waxay ku dhacdaa inta u dhaxaysa ±0.5% ilaa ±5% ee akhrinta, iyadoo xaalado gaar ah ay yihiin sidan soo socota:
- Moodooyinka saxda ah ee sare: Ku habboon shaybaarrada, xakamaynta saxda ah ee warshadaha, iwm. Gaasaska nadiifka ah (sida hawada, naytarojiinta) ee ku jira heerka socodka la hagaajiyay, saxnaantu waxay gaari kartaa ±0.5% ~±1% akhrinta, qaar ka mid ah alaabada heerka sare ahna waxay xitaa gaari karaan ±0.2%.
- Moodooyinka guud ee warshadaha: Waxaa loo isticmaalaa la socodka habka caadiga ah, iyadoo saxnaanta ugu badan ay tahay ±1% ~ ± 2% akhrinta, taasoo khuseysa dareerayaasha caadiga ah sida gaaska dabiiciga ah iyo gaasaska habka loo isticmaalo.
- Xaaladaha gaarka ah: Marka la cabbirayo dareerayaasha xawaaraha hooseeya, kuwa aadka u dhuuban ama dareerayaasha ay ku jiraan xaddi yar oo wasakh ah, saxnaantu waxay hoos ugu dhici kartaa ±2% ~±5% akhrinta; haddii sifooyinka dareeruhu ay si weyn uga duwan yihiin kuwa la hagaajiyay (tusaale ahaan, iyada oo aan dib loo habeyn), qaladku wuu sii kordhi karaa.
Intaa waxaa dheer, ku celcelinta (xasilloonida muddada gaaban) badanaa way ka fiican tahay saxnaanta, guud ahaan gudaha ±0.1% ~ ± 0.5%, taas oo aad muhiim ugu ah la socodka socodka firfircoon. Codsiyada wax ku oolka ah, waxaa lagama maarmaan ah in la doorto qaab ku habboon oo ku salaysan xaalado shaqo oo gaar ah (sida nadiifinta dareeraha iyo heerkulka) si loo hubiyo saxnaanta.
