BCI command accuracy.

<p>For the sake of clarity, accuracy in the figure is reported per session instead of per race. <b>(A)</b> Average within-session BCI command accuracy (in percent) for pilots P1 and P2. Spin command accuracy shown in cyan, jump in magenta, and slide in yellow. The dashed black line shows the overall accuracy (average of individual command accuracies) in a session. The Pearson correlation between the overall command accuracy and the chronological race index is also reported (significance tested with Student <i>t</i> test distribution). <b>(B)</b> Average and standard deviation of BCI command accuracy (in percent) for pilots P1 and P2 for all command types (cyan for spin, magenta for jump, yellow for slide) and overall (black) in the first and last four training sessions, including the competition day. Statistically significant differences are shown with two-sided Wilcoxon ranksum tests, (*): <i>p</i> < .05, (***): <i>p</i> < .001.
