While doing some Black Friday solo runs, I noticed something strange regarding the AI teammates. If they are present during the run, then the alarm will sound instantly, since the armed AI teammates will spawn at the door of the mall. However, without AI, the alarm does not instantly go off, and the player must pass near the door in order for the alarm to sound. While this seems insignificant at first, I also found that without AI, it takes longer for Jade to give the first objective (about 3 seconds longer than if there are AI; first objective w/ AI is given at around 19 seconds, whereas without AI the first objective is given at around 22-23 seconds, which coincides with how long it takes to run to the door to sound the alarm if no AI teammates are present). If I were to do the run without AI, would the extra 3-4 seconds of wait be subtracted from my total, or would I just have to play with AI in order to get a better time?
