Yes, people trip if it is not. Remarkably almost all cultures use the same ratio.
The run is always longer, if not, I bet your staircase does not meet code
Either can be bigger: it is no big deal.
A spiral staircase does not provide a greater mechanical advantage than a steep straight staircase; in fact, it typically requires more effort to ascend. This is because a spiral staircase often has a tighter radius and requires a greater vertical distance to be covered for each step, leading to increased exertion. While spiral staircases can save space and add aesthetic value, they do not reduce the effort needed to rise vertically compared to a straight staircase.
It is harder to build a spiral Staircase because if you build a spiral staircase it will be longer and twistier than a straight staircase.

Rise over run is used to determine slope. It doesn't matter which number is bigger. It simply tells you how far up a slope climbs over what distance. So on a roof for instance, 4/12 means the roof climbs 4 inches higher every foot of width.
