We talk of normal tense in this part if the tense is formed only by one word. Composed tenses have a form of haber or estar as the first part followed by the particip or a gerund. Because haber and estar are always conjugated the same way the composed tenses are considered easier and they should not ask as often as the normal tenses. You can set the proportion here.
/ normaalne asukohas part kui on x üks a vorm / või kui part x või a ja alati ja mitte küsitakse kui sageli kui normaalne Mina.
