 __**Library Summary Comparisons**__
-The library summary represents a mean signal derived from a large number of individuals, providing a baseline of what is considered a typical movement for the general college pitcher population. By using this as a reference, you can see how the elite pitchers deviate from or align with the general college pitcher population. By using this as a reference, you can see how the elite pitchers deviate or align with the general population.

 The SPM plot analysis, using an alpha level of 0.05, reveals a critical t-statistic threshold of 2.73, indicated by the dashed red line at the top of the graph. This threshold represents the point beyond which differences in shoulder angular velocity (SAV-Z) between elite pitchers and the general collegiate population would be considered statistically significant. However, throughout the entire range of normalized motion, the observed t-statistic consistently remains below this threshold, suggesting that there are no statistically significant differences in SAV-Z between the two groups.
-Despite this, the curve's jagged shape indicates greater variability in elite pitchers' SAV-Z, especially in the early phase of motion, highlighting the complexity of elite pitching mechanics.
