I'd go with TC :

- if it works as far back as the driver's helmet, those 3 circles above the seat are likely intakes ? Then it could help there as well .
- maybe even out pressure over the vent hole, rather than have a pulsating effect ?
Have you ever driven a motorcycle with an ill-adjusted or ill-conceived screen ?
The buffeting is debilitating.
One way to solve this buffeting is dimples - which are VG in the gliders' world
- near the top of the screen.
