This has been consistent with me and I found this faster than turning around. This was done on the PS4 just in case if anyone was wondering.

So I was on the quest to get the circular saw and I think I may have found 2 possible time saves? I am just talking whatever right now but I guess if anyone wants to try and see if it saves time for them.

1. This occurs when you first meet Tubby Tubs(that's just my name for him). Since I did not have the circular saw while playing this, I was trying to see if I can get a head start by shooting Tubs while he was going down the elevator. Sure enough it worked. So possibly he can go down faster with the saw once the doors open?

2. Again since I did not have the circular saw i was trying to find another way to beat Eveline faster. So what I did was I used 2 remote bombs, the grenade launch and one shot from Albert 01-R.

Again I don't know if these will actually save time in real runs but they worked pretty fast for me when since i didnt have the circular saw.
