The performance of a crossbow = how much energy can be transmitted on the arrow independent from draw weigths (lbs). The rule of thumb is:
A crossbow with a draw length (= distance from the chord’s rest position to the lock) less than 10 inch (approx. 25cm) can not achieve the power of modern high-performance crossbows. Even if advertising draw weights of 200lbs and other superlatives, you should not be deceived.
However, the cross-recurve-spool-system of the swiss manufacturer “Swiss Crossbow Makers” is an exception. This system tightens the chord in 4 points simultaneously producing extraordinary fast propulsion on a distance less than 8 inch.
