I think they should change the "sinking" part of it to clearly state if the skier or binding causes the "sinking" then it will count. To me, what makes sense is if the ski is outside of the buoy, scoring follows the quarter, half, full, rule. We have all hit buoys with shins, ankles, bindings, etc. and dunked them. If the ski is outside of center on the ball, it should count. If the ski is on the inside of center, then no good.
