Pit stop times

I'll start this by letting David know I searched the forums and didn't find an answer... :)

I'm curious to know if there's been any evidence of anything a manager can do to improve pit stop times? In my last race I noticed what seemed to be my only real competitor get a few pit stop times with quite a bit lower time (nearly 20% or 1s). I wasn't sure if there's some staff skill level that affects this, or if it's completely random, or just what might affect it. I've already seen that it doesn't appear to matter if I put 10l of fuel in, or 50l of fuel it still takes roughly the same time (though some variance occurs even with identical fuel levels each stop). I read a few forum posts about other pit stop issues like blocking/holding up others, and unscheduled stops and such but not much about the actual time reported in the post race report. With the last race being decided by about 0.5s (apparently couldn't pass him for about 5 laps...) I wonder if I can adjust something in my training to help improve on this or if it's completely random or decided by some other factors. Whenever the next patch that's been talked about as long as I've been in the game finally gets released, may have to re-learn yet another aspect as the various answers from devs indicates a few changes to pitting results.

Any insight is appreciated, thanks.

I though teamwork helped pitstops bit i still think its a bit random.

I'm pretty sure it's just random. My drivers get awesome pit stops (generally speaking) and I'm pretty sure my team work rating is like 1 (I barely ever train technical or mental)

Edit: Yeah, my team work is 1.

I'm currently working on a design model for Jack and Andrew to look at which will effect pitstop times.

Ok, so I'm just lucky enough not to get lucky for pit stops during my races and get a 4s instead of 5s one, go me! :) I REALLY hope this next patch makes a bunch more relevant, fiddling with numbers make my brain happy. So far they just look pretty so I'd like them to mean something soon to appease the brain. At least I had some fun determining an income calculator for the marketing side of the game, too bad it's also pointless haha
