Note that the function for splits versus power expended is exponential--that is, the lower your splits, the more difficult it becomes to lower them further because the change in power becomes so steep. Also note that power and energy can be used synonymously when discussing percent expended; the relationship between power and energy is linear (power = energy over time), and although power (wattage) is produced by the formula, the final result of a percentage allows for the use of either unit.

A lightweight rower experiences no advantage on an erg—heavier rowers have more muscle weight and can thus use this muscle to pull harder. However, the lighter a boat is on the water, the less the resistance generated by the depth of the hull in the water. Therefore, weight adjustment translates erg scores into projected on-the-water times should both rowers row the same race. Note that this formula is fairly accurate only if the test is longer than two minutes.
