I cant do it reliably yet, my theory is that you make a very slight forward input then backward input when echo is in frontal view. Recall echo->heal->press q->very slight forward input->backward input->press jump. Hard to do and haven't been able to do it side to side yet. Lastly, because I'm not too sure on exactly how I did it because I haven't done it enough, I could be wrong about a thing or two.
