On this I agree. Once your daughter really feels what it's like to coil around the rear leg with the rear butt cheek she will then understand what it's like to be one legged. And then she will also learn the timing window you get from being one legged if you maintain the coil. It doesn't matter if you stride or not.
Agree and I like your simple post. You hit from the backside, trying to hit from the front side will only result in lunging of some sort.
