Restart states from Rev 205 and Rev 206 give similar results. Below are the following differences and errors

MMS	Plan-OD Rev 205 states	Error wrt Rev 205 states	Plan-OD Rev 206 states	Error wrt Rev 206 states	
	A (km)		A (km)		
MMS1	0.01405	-0.16%	0.02007	-0.23%

The Table below provides the following information:
•	First row for each maneuver: planned maneuver total delta-V values based on the associated DVTABLEs  
•	Second row for each maneuver: associated final maneuver planning requirements 
•	Third row for each maneuver: predicted velocity error at the time of the maneuver computed by differencing the predicted velocity at the maneuver time (starting with the post-perigee GEONS state prior to the maneuver) vs the definitive GEONS state at the time of the maneuver.
The predicted velocity met all requirements with significant margin except for the requirement highlighted in red below.

All FR202 and FR203 maneuvers were planned using predicted ephemeris files based on GEONS post-perigee RST vectors @ 2015-271/04:41, one day prior to the CAM.  Note that these predictions start 2+ orbits prior to FR202 and 3+ orbits prior to FR203 because the FR202 maneuvers started only a couple of hours post-perigee,  CAM was held the prior day, and final maneuver plans had to be prepared prior to the CAM. A “tweak” was planned for FR203 but decision was made to use the original plan.
