and "a continuous rate one climbing turn onto downwind" is in,
Why only a rate one turn? The rate of climb in a 30 degree banked turn is almost identical to that of a rate one. You would never pick the difference in the short time it takes to turn through 90 degrees. In a Cessna high wing type the blind spot during the turn means you spend more time blind at Rate One than if the turn is steeper for a shorter period.
The Rate One climbing turn harks from the old days in Tiger Moths where a circling climb to height prior setting course for a cross-country from over the field, was best done at Rate One in order to get to height more quickly that a continuous steep turn over the field over a smaller radius. Nothing wrong at all with a 30-35 degree angle of bank turn for the first crosswind leg -straighten up for a few seconds for spacing and a good look around, then same bank angle on to downwind. Same on base and final.
