Keep Your Foot on the Pedrogas Not Unlocking?

I have just added up my combined times for Halo: Reach and they come to a total of 179.1. I didn’t commit suicide on Lone Wolf which is normally a contributing factor towards the achievement not unlocking and I let the cutscene play out. The mission before that, Tip of the Spear, I actually beat the par time on (I got that achievement) so I know it’s nothing to do with my console acting up. Do I need to get my times down a bit more? I shouldn’t have thought so as three hours is 180 minutes. What am I overlooking here?

Update: So I figured out what I was overlooking. I accessed my in-game stats in the game itself and it reads 3:01:03. Unless my phones calculator is faulty, I wonder why the two times are completely different? Well, looks like I’ve got to get my times down some more.

Second Update: Got my in-game time to 2:51:39 and still nothing has unlocked…

Third Update: For some reason replaying Noble Actual unlocked the achievement. Anyways this thread can be closed now.

Did you skip the cutscene at the start? Because if so, then that is why, glad it’s resolved!
