Hope it has a slightly improvement in existing matching system (not for 2v2 arranged)

I don't know it is system design or a system bug

Dr. Ghost 35 (P1) and J1flash (P3) are 2v2 Arranged master players
[<Mars>] (P2) and Gamer1357924680 (P4) are ST and gifted random players.

Scenario 
P1 joint the game
P2 joint the game 
P3 joint the game ~1.5 days later
P4 joint the game in few hours later

My question is: did the matching system count the total time for pairing? When it reached 1.5-2.0 days, it started to give them *something* to play. If this is the case, P3 can do something really hurt the matching system.

PS. I will also post it in Bug Report Thread
