So my google-fu is failing me so I'm hoping someone can help out here.

I've been reading up on chase orbits and how things like the Shuttle, dragon, etc all approach the ISS and I understand the process, what I cannot find are the formulas to work out the distance between the chase spacecraft and the ISS or the per orbit catch up rate.

Can anyone help me find it?
