That makes sense to me. The more point weight, the more the arrows are initially forced to flex, which also means the more variations in the arrows flexing are going to have an effect on arrow flight.
I can in-vision variations beyond the direction of flex and the amount of flex, such as where along the arrow it flexes (front to back), and even the possibility of the amount of time it takes the arrow to stop flexing (number of oscillations).
