damed if I know, but what I do know its good to ask a of of questions It common for the layman to want simple answers for complex issues which can lead to doing an ineffective thing,
In this case having the string in the centre or a few degrees to the outside, it may in the overall scheme of things make not discernible difference For example if the glider settles and it easier to maintain a steady climb with a few degrees of offset yaw, it might be less drag than futzing with the controls (creating more drag) to keep in the centre. Additionally putting focus on the string means that the pilots mental focus is not on something else (like staying in the core or not adjusting to being blown out by horizontal gusts), hence there is always tradeoff. If there is gain, it might be so small as to not warrant the attention tax.
