I believe you about the timeline it fits with what i thought and have heard GL say. Where exactly on the bonus DVD?
I always thought that significant amount of time would have to pass between ESB and RoTJ so that we as an audience buy the idea of luke being a jedi, but at the same time how long would it have taken to formulate the plan to rescue han solo? Seems to me that they wre just chilling for a while at Han's expense
