$650 bonus for PlatinumStar means $0.013 / FPP, what is $ 0.0325 / VPP at this VIP level.

I have no idea what's the rake in NL games @ Stars, but playing 1/2 FL SH gives you $1.56/100 hands (39 VPP/100 hands * 2.5 (PT multiplicator) * 0.013 (value of 1 FPP)), what's the same as ~26% effective rakeback.

Don't forget if you are able to get to PlatinumStar, you will achieve SuperNova level sooner or later, which means +23% value of FPPs (if you use $4k bonuses), so effective rakeback would be 32.5% (from your old saved points) and 40% since you reach SN status.

There's $50 deposit bonus at Stars and 2 regular reload bonuses ($150

) per year + some special from time to time (like $250 2 weeks ago).
