the entry system is the rankings <img src="wink.gif" border="0">
the Champions Race only counts points on the ATP tour.
so no challengers are included , so that would mean new players could never gain a decent rank if only the RACE was used for seedings/entry purposes
therefore the REAL RANKS are the entry system which count all the events from futures to slams.
<br /> Entry System points are x5 whatever is earned on the RACE
