I have added a new tab called recent performance. It has charts that show year to date performance, as well as last year's performance. The charts are linked with a Google Doc that I created, so they should update automatically. If you are periodically curious to see how the PP is doing, this tab is for you.
The charts track all of the components of the PP, the PP itself, and inflation. This should give you all of the information you need to see what is driving the PP, as well as its inflation adjusted performance.
