So something people who run Alien campaign may have noticed is that during the tutorial Dr. Groves skips a couple lines of dialogue after you defeat the armed test subject, prior to the Queen cutscene. It's only like 5-8 seconds. But in a 14 minute run, every bit helps y'know.

Those lines seem to be cut if he hasn't finished the previous line before you kill the subject.

The dialogue after you hiss: 1.) "Caution, Six? A strong indicator of intelligence." 2.) "But how do you know of the threat?" [Potential Skip] 3.) "Mr. Weyland WAS right." 4.) "Very good." 5.) "That's enough for today, I think..." [Queen Cutscene]

I've found the easiest way to repeat the skip is by waiting until after Groves says "Caution, Six?" before you even enter the room. Then just close in on the subject and grab and kill him. The timing takes a bit of getting used to, but that seems to be a good general guideline.

Here's an the skip in action:
