Just wondering. I saw you did it in your New WR, does that actually save time?

I can't quite tell, it seems like it does as you're doing something mid-cutscene. Also it does mean you only have to speak to the tribesman once after the duel. At a guess it probably only saves a second, maybe two at a stretch.

I think the best way to use it to save time would be to try and talk to the Native American twice before the game, so during the duel you can have your cursor waiting where the totem is. I was almost able to do that in a run but then I misclicked on the dialog and it slowed me way down.
