How are you getting your Delta V values for this burn.
I get my DV values by doing this (according to the Apollo 7 Flightplan vAGC.xls):
MFD1 Open Interplanetary MFD
Click "MNU"
Click "MOD" (Configuration)
Click "NXT" until "LambertAP Mode" is selected
Click "+" to select "Apollo P30"
Click "MNU"
Click the "Course" button
Click "NXT" until "Delta Velocity" is selected
Click "SET"
Click the "+" or "-" buttons until the GET displays the time of the burn in the table below. Use "ADJ" to adjust the increments as necessary
Click "NXT" and use the "+" or "-" buttons to adjust the "dVf" and "dVi" to the base velocities in the table below to start with
Adjust "dVf" and "dVi" until the ApA and PeA relate closely to the base ApA/PeA in the km column below
MFD2 Open Project Apollo MFD
Click the "IMFD" button
Click "REQ" to request burn velocities from MFD1 in ft/sec
Click "BCK"
Click "TELE"
Click "P30"
2 UPTLM/CM - ACCEPT (UP)
MFD2 Click "P30" burn data will uplink, wait for UPTLM light to extinguish
2 UPTLM/CM - BLOCK (DOWN)
