Hi Jared,
It takes about 5-6 images before you will start to see anything on the graph. During that time PEMPro is building a linear best fit line and/or making sure there the star is stabilized. Looking at the end of the log the star must have moved a lot, causing a huge swing in adjustment (probably off the graph):
