Do you use the loaded Dix-Hallpike (D-H) test by Dr. Jeff Walter's team (Andera et al., 2020)? It increases sensitivity of the traditional D-H by 13.1%! The loaded D-H helped me catch a subtle left posterior canalithiasis BPPV case that I didn't see with traditional testing even in infrared video goggles (video clipped for brevity - the patient did hold the seated position with neck rotation and flexion for 30 seconds as recommended).
