Some years ago me and a mate fired our spearguns (without line attatched )out into a field to see how far the spear would go ,as a way of comparing / measuring power , today there is no 'rating ' system for power ,eg foot per second or range ,but generally if it takes a lot of effort to load it should have more power .
