Wind power as a function of time for a YMSC with 10³ M_⊙ (upper plot) and 10⁴ M_⊙ (lower plot) is shown as a solid line. The shaded region shows how the wind luminosity can statistically vary for different random sampling of the initial stellar mass function. The limits of the shaded region are calculated as the 10% and 90% percentile out of 100 possible samplings of the initial stellar mass function.
