The formula for a windlass is 4s * (BL for rated bow ST) / (BL for wielder). If we assume that a crossbow with a rated ST of 10 is an 80 lb bow, which is at least believable, just go with 'poundage/BL seconds'. I have no idea why the weight of a windlass would vary significantly with its strength ratio in the first place, you adjust the strength ratio by just changing the ratio of shaft radius to arm radius. You need stronger structure (and cord) for a stronger bow, but the weight increase shouldn't be very large and in any case is only dependent on the draw weight of the bow.
