SA,
I cannot answer that one as I have never chronoed it. I can though and will this weekend...as well as the Pat SC since I have not chronoed that either.
My typical seutp these days is either a 30.5 or 31 inch draw length, 430 grain arrow and a 70 lb draw weight. I was shooting 65 lbs for quite some time but the draw cycle on both the Rhino and the Pat SC seem to allow me to pull slightly more weight comfortably.
My typical speed with most of the other " shorties" that I have been shooting in recent years has been in the 270-280 fps range with the above mentioned setup and a 65 lb draw weight. I am expecting around 270 fps with the Rhino despite the extra 5 lbs of draw weight simply because the brace height is rather large at 8.5 inches and the draw cycle is relatively smooth.
I can let you know more later if you like. Perhaps a " mini-review" ....
