Group I - 1,000 points
Group II - 400 points
Group III - 160 points
Maximum points/number of ties played = roughly the points given for each win.
Does it mean the finishing position doesn't matter - only the numbers of ties won?
It doesn't seem the case, as Israel should have much more points if that was true.
Also, it says in the fed cup site:
"In the Groups I, II and III a nation's points are determined by its overall finishing position."
