This is out of my 2004 owners manual:

"Speeds for the Blackhawk2 and ladyhawk are based on a 300 grn arrow shot at 60 lbs with a 26 inch draw. The Rascal speed is achieved using a 200 grn arrow shot at 40 lbs with a 25 inch draw."

The website sort of suggests the same thing as it lists what draw length the bow was shot with to acheive the listed speeds. It doesn't say anything about the draw weight and arrow weight though.
