There's a constellation of youtube videos on the technology at https://tinyurl.com/yb7h38kv This design is not limited by friction but by the relative hardness of washer and that of the nut and base surfaces. The outside faces of the Nord washer pair must displace metal and 'dig in'. I suspect that star washers, fabricated from steels on the same class as Nord washers would see a quantum jump in performance.
