I see Paul has posted some of the potential gains

I asked RJS if that sheet could be posted here so you all could run your own scenarios - it is a relatively simple Excel sheet with a couple of variables. Unfortunately, RJS says it can't be attached here.
I will post a couple of scenarios with my assumptions taken from the sheet. After you see what it produces, if there are any specific requests, it won't take long to recalculate - it might take me longer to post depending on how busy I am! I'll start a new thread behind this one with the first iteration with assumptions.
