      ] This indirect marker is presumably relied upon because it is difficult to accurately measure competency. However, the relationship between scan numbers and interpretation accuracy is not well understood. Prior studies on POCUS learning curves have demonstrated variable results pertaining to scan numbers and image interpretation amongst various applications [
