I learned that chazarah is something very different: it should be short. R’ Moshe Feinstein told the boys – and practised it himself – that one should not relearn the daf, rather read through it without concentrating too much. He said six minutes a daf. Only Chazer the gemarah, not rashi or tosfos (although naturally you will be learning the sugya with their perush) because you will get bogged down. Chazzar while the subject is fresh (as the gemarah says, Atiki kasha machaedta). Chazzar three blatt a day.
Chazzarah is a flow. It is enjoyable to relax and let the familiar words of the gemarah flow past. Most people who claim that chazarah is hard and that they have no taam in it are simply doing it wrong.
