Kukuyiphi i-% yesikhathi sosuku lapho zombili izandla zewashi le-analog zisengxenyeni efanele yokudayela? Okokuqala, bheka ihora lesandla, elisesandleni sokudla njalo ngamahora ayi-12 kwangu-24 (50%). Kusukela ngalesi sikhathi isandla seminithi sizoba sesandleni sokudla emahoreni ayi-6 kwangu-12 (25%). Kulawa mahora ayi-6, isandla sesibili sichitha amahora ama-3 ngasohlangothini lwesokunene (12.5%).
Le ncazelo enembile nayo kulula ukuyifakazela:

Amathuba awavumelekile kuphela engxenyeni elungile yobuso bewashi, kepha kunoma iyiphi ingxenye.
