there is a plotting graph of a reverse drift simulation of body #3z, showing the different origin points depending on whether the body was 40%, 50%, 70%, 80%, 90% or 100 percent immersed. The different origin points span about 20 minutes of longitude, and the maximum distance traveled from simulated origin to recovery was nearly one degree of longitude.
