is here any advantage to the exaggerated roll?
This is just a suggestion.
One thing that disappears from some archer's shots, is a natural follow through. It seems they don't have one; perhaps they have lost the habit or never had one.
In golf there is a clear follow through, especially when using a driver. There's less of a follow through on short putts.
In archery there is a follow through, especially with faster recurves compared to beginners' 16lbs bows.
The follow through is important but it can become lost or cut short. Cutting short the follow through sometimes means the archer is cutting off the shot process a bit too soon, anticipating perhaps and stiffening up.
A bow that rolls CAN be a way of making it more likely that the follow through is being allowed time to take its natural course. Imagine a golf drive with no follow through, the club almost demands one. The putter doesn't demand a follow through in the same way. Perhaps a bow that does nothing at the end of the power stroke is less inclined to encourage the extending of the shot beyond the release. I am thinking that top archers can probably work without these helping hands, lesser archers may be helped by such things, as a reminder or double check.
