MechJeb and Orbital Rendezvous

[LittleItaly]

I'm not sure if this question belongs here or in the Add-Ons forum, but I am having problems with MechJeb's Rendezvous on Ascent function on the Automated Ascent screen. I understand that you select a target and it time accelerates to put you in relatively close orbit to the target (in this case a space station). In all the vids I have seen, this "relatively close" distance is about four kilometers, but I have done over a dozen launches using this and the closest I can ever get is 100 kilometers. Am I doing something wrong? Thank you!

Assuming you're using the old 1.9.8 version of MechJeb, it assumes that the launch profile is identical to the rocket that was launched previously. If you are using different launchers/spacecraft, the the phase angle will be different.
