Error plots (min, lower quartile, median, upper quartile, max) for each algorithm from Table 1, estimating Foot Strike and Foot Off compared to rater expertise. The light green areas come from the inter-rater reliability evaluation (Fig. 4). Dark green areas are the Foot Strike specifications applied on Foot Off
