CPQ2 medals

Basically my situation is this: I am CPQ2ing and I want to get the 10 stat medal and a lot of wins (more than that of the first place guy) in order to make it last longer, but i don't need the 7 stat medal, and i don't want the current holder to lose it. However, the medals are given to the person ranked #1 only in the server, only 1 person can have a medal at a time.

What i want to know is, how are the medals removed from their current holders?

is it automatically removed when they are outranked? or do i have to complete the medal quest and actually get the medal in order for the current holder to lose it?

is it possible that i just get the +10 stat medal and get more wins than first place but still have him keep the 7 stat medal because i don't click "i would like to compete for the 7 stat medal challenge"?

NOTE:
The 10 stat medal quest name: "The Gifted Carnivalian"
The 7 stat medal quest name: "The Carnivalian Of Absolute Victory"

NOTE:
-you get the 7 stat medal by having the most wins hands down
-you get the 10 stat medal by having the highest win percentage, in the case that 2 people have the same win %, the one with the greater # of wins gets the medal.
