The predicted and actual repetitions to task-failure in the squat stratified by set, load, and trainee. The actual number of repetitions left for each trainee for a given time-point is represented by a cross. For each trainee, the predicated number of repetitions given by each coach is represented by a single-colored dot. The distribution of coaches’ predictions for each trainee is provided by a consistently ordered and colored boxplot. For example, at the top left panel, the black horizontal line in the leftmost boxplot (at the 33% mark, in red) indicates that the coaches predicted a median of four repetitions left for this trainee at the first prediction point, at the first set. However, the actual number of repetitions left for this trainee, under that condition, was 10 (black cross). Moving to the following prediction point (66%), for the same trainee (red), under the same condition, the median predicted repetitions left was three, whereas the actual number of repetitions left was five
