In the original article, there was a mistake in Table 1 as published. Incorrect values for Power Output (W) were entered into Table 1, as the original publication includes log units instead of Watts. The corrected Table 1 appears below.

Mean is the mean of the crew means, between-crew SD is the SD of the crew means, and within-crew SD is the mean of the crews' SDs across their one to the three races (~250 to ~750 strokes).
Number of crews: 10, 8, 3, and 6 respectively.
Number of races: 17, 13, 5, and 12 respectively.
