What steps have you taken to reduce time wasted in Party Finder?

I made the stupid decision to get the Shroud of Darkness, so I've been spending a couple hours a night in there. I'll share what I've done to save time, if you share. Not that it matters for me anymore, I'm done now.

• Only joining groups that need five or fewer players unless there's a "checking for 10+ clears" party
• Not giving groups a full half hour if there are obvious problems (leaving if there is less than eleven minutes left on food)
• Never forcing myself into a position assignment (expecting other players to be worse at adjusting, less experienced)
• Screening of the Alliance leader and my party
