It was fun to go for a better F.N.G. score in CoD 4, but now MW2 has a trial at the start of the game. This is about the campaign version where it includes specifics.
 
What are your best times? Also what weapons did you use?
 
28.3 seconds with 50% accuracy using an MP5K and a Beretta M9.

56% Accuracy 
Using: MP5K and also the Beretta M9 
My best time was only 30.4 though :(

28.5 with the two handguns, 100% accuracy. If I retried it a few more times I could probably get over 100% accuracy (due to penetration) and reap the bonus

Not sure what my accuracy was but I used the Beretta M9 and the MP5K and only got 31 seconds... I'm slow i know

Dude, does anyone have any tips for completing this under 30 seconds? I just tried for the third time and I got around 35. Is it okay to shoot from the hip on a couple targets? I get yelled at for doing it, but it does seem faster...
 
Also, I just use two rifles, maybe I shouldn't do that? I'm still not too familiar with the different guns, but I don't bother with the pistols. I was able to get under the target time in COD4... I thought that training stage was better.

Can't think of it off the top of my head, but running the Pit... in Spec Ops I got 29.9. Yes, that means no Accuracy bonus time given. Should have read the achievement requirements first, lol.
 
That being said... I used the MP5 and the M9. Don't jump over the hurdles, move around them as you shoot the targets.  Don't shoot from the hip, aim down the sights to hit the target the first time while keeping as many bullets in the chamber to avoid reloading. Another tip would be to try and hit two targets with one shot after you run up the stairs.

Two handguns are the best . Especially the socom with the knife

The fastest I could get was something like 31.4 with 2 pistols.

I did it in either 26 or 28 seconds.

29.1 sec. 100% accuracy. MP5K and USP

Finished it with my best.
 
26.75 with M9 and Desert Eagle.
 
150% Accuracy = -7.5 seconds = 19.25 overall.

I made a thread about this allready. 
but anyway: 
25.5 
100% Accuracy 
with M9 and USB.45 
 
update 
23.2 
125% Accuracy 
same guns

29.85 sec with the MP5 and Machine Pistol thats available, dont know its name.

They should have leaderboards for pit times and Spec Ops stuff. My best pit time was about 29 seconds with the accuracy bonus.

haha i pooped my pants when the GUY first yelled at me "

25 secs or somthing

i did 28 before the bonuses
 i think it was like 23-24

27 on PC, 29 on 360.

I haven't done it apart from at the beginning of the game, can't remember what time I got though.

25.7 seconds with 100 % accuracy

" 28.5 with the two handguns, 100% accuracy. If I retried it a few more times I could probably get over 100% accuracy (due to penetration) and reap the bonus "

28.5

27.3 with the MP5K and the Beretta M9.  90% Accuracy.

It was only after a few goes that I realised the accuracy bonus could go over 100% so I'm on a time of about 26 seconds.

I got 28 seconds with about 50-60% accuracy. I used the M4A1 and an M9.

As soon as I got the trophy, that's pretty much all I gave a shit about. Though, I think the lowest I got was exactly 30 seconds.

28.4 with 120% accuracy and I think I was using a USP with a tactical knife.

My time was 28 seconds using only the AK-47. Never needed to reload.

I got like 21.3. I just used two pistols and the tactical knife for the fastest time.

I shot two targets at once and got a 108% acc. It was pretty sweet. 
 
Oh and 26 seconds.

Hey guys... just got 19 seconds on pc...
