Disagree DFC. I taught on the Robin HR200 with just over an hour on type. However I had 400+ hours fixed-wing, on 9 types, including over 70 on 2 types with very similar handling. Combining all my experience teaching on the Robin was far from "blind leading blind". The judgement should be by individual case - a reputable school ensures that students get good quality of tuition. The regulations you seem to recommend would have been an unnecessary burden. As suggested it seems they will not be.
