So - you are using a linear relationship between power and speed? Care to explain?
My quick estimate was by the square root of the increase of power. Also how do you know the weight? Any flight test program I've been involved with at Sikorsky has never been anywhere near empty weight.
IIRC you said you were a key player on the X2, which means you know the effect weight has on speed for an X2 rotor.
Edit: my bad, you said you did a bit on X2. So maybe you don't know.
