Here's a breakdown of three days of observations from the USA 328-331 
mission. What the data reveals is that three of the classified objects 
appear to not be changing their orbits while two others appear to be 
perhaps constantly doing so.

The five objects appear in a stretched out train now with 99991, 99992, 
52889, 52893 and 99993 appearing in this order. I've chosen this naming 
criteria based on two factors, order of their appearance and in the case 
of an ID to catalogued object the object that closest fits it (most 
often) based on the epoch 22173 TLE set published in the classfd.tle 
file by Mike McCants.

I then took the three days of observations, made the assumption that the 
appearance of each object in the chain means it's the same object and 
then fit 99991, 99992, 99993 and 52889 to the 52889 TLE with the epoch 
22173.

I fit the 52893 object to the epoch 22173 for the same object.

Here's a summary plots of the three day's of observations:
