In that respect it is not very different from ATP race list, where everybody starts with 0 points. So, if Federer beats Tomic, he would then have 412 points, and Tomic would fall to 388 points. But, with ATP point system it is not the same if Federer beat Tomic in final or in R32 match, whereas in Elo system it is not important in which phase of the tournament a player wins.
You're thinkin 12 as quotient, I see. This could conceivably be higher for important tournaments and lower for unimportant ones.

It will take a long time for rankings to show a true picture if a victory over Federer initially is worth no more than a victory over a 16-year old WC in his first ATP match.
