you go to http://www.pokerstars.co.uk/vip/tiers/
and click the page for your VIP level
then click the goldstar rewards value tab in the table
find the % that applies to you
the higher % of the two in the brackets is for FR cash, the lower % for every other game type, 6max, SNGs etc.
read the fine print to understand the two column headings
