Question on Oro's dash properties

Is there anyway to tell at which frames oros dash will go under high attacks. The only time i get this is off is with luck. I tried testing dashing under a hadouken but the timing is off im thinking becuase im have trouble doing it. Can anyone confirm the properties of Oro’s Dash?

You must dash at the last second before the Hadouken hits. Only the first couple of frames of Oro’s dash will go low enough.

I’d link you the dash frame data, but is dead.
