What I meant was the bottom chain doesn't move ONLY IF the top doesn't move. you are trying to work out whether or not the top part of the chain moves. You can't say the top does't move because the bottom does as the bottom's movement is dependent on what's going on on top.
I guess I found equations to be far less brain hurt
