In the text, it was emphasized that the derived power equation does not require phantom subjects or calibration to be used:  "\textit{We emphasize that the use of phantom subjects do does  not directly contribute to the power equation in Figure 1, as it does not account for any sort of calibration or scaling. However, it requires an estimate for $CV_a$, which is the variability of scaling biases between sites. The goal of this study is to provide researchers with estimates of $CV_a$ from our set of calibration phantoms and our set of non-standardized MRI acquisitions. For a standardized set of scanners, these values may be considered an upper bound. }"
