Stars FPP/VPP monitoring

[MrBananagrabber]

I'm trying to compare PokerStars' FPP & VPP system to other rakeback schemes in order to determine whether I should play there or not. For the last two months I've made GoldStar without really trying, and I can make PlatinumStar if I focus. Lots of people don't like Stars because you don't get rakeback in cash, yet there are lots of items in the FPP store that I plan on buying anyways (e.g. iPods, monitors, DVD players). But I don't know any smart way of tracking my FPP & VPP accumulation in order to calculate an hourly rate, so it's tough to compare to other rakeback schemes.

For those of you playing seriously at GoldStar or above on Stars, what do you use to monitor your FPP accumulation? How do you know if you'd be better off at Full Tilt getting cash rakeback?
