Time wise which is the best method? Using the target locator or doing firefight matchmaking?

Also what if I go over the daily credit(200,000)cap?
From what you’ve suggested, Target Locator (but that’s not really sporting). Note that under normal circumstances Gruntpocalypse doesn’t score that high, it’s only when 343i put on the occasional 5x bonus that you’ll get that level of cR return.
If you optimise your Grunt targets, use Medals instead of Headshots and turn-in completed challenges after 2 games and recreate them, you can get over 50,000cR for 4 games when the 5x bonus is active.
If you go over the cap you won’t get the extra cR. I’ve heard that if you do challenges offline and exceed the cap, when you go back online your cR will reduce back to what you would have got if you’d been online all the time. Don’t know if anyone can confirm this though.
