[@AdorableSaucer]So if someone takes an action that lasts a longer amount of time and another takes an action that lasts a shorter amount of time, the time that ellapses in that turn is the time it takes the person doing the longer action to complete that action? If that makes sense

If so, what is the person with the shorter action doing in the meantime in-universe? I suppose that would mean that the shorter each action you do is, the more of them you can take? Or it allows you to take an additional action to compensate. Or is it just an impromptu "wing it" sitaution
