Housing Shrinkage Calculation
Shrinkage was calculated by measuring 3 yoyos from 6 different molds with varying thicknesses, plotted in the following graph as a function of their thickness. A region & ballpark was identified.We then calculated a weighted average using only data from nearby thickness profiles.
