Hi Barry,
I did try all these, it is nor that flexible, it locks the riser height thus resulting in certain inclination, does not play with the range of riser. Maybe the problem is in RC1 release, still haven't got my upgrade.
And by the way, I was thinking that this should be implemented for the concrete stair structure. Also to control if the difference in height is very small and the length of tread large, to turn to ramp for that segment.

A single Stair's Risers Height and Going Depth is always the same when it is placed. In Edit Mode it is possible to move all Risers to some other position (please note that this will not modify the Structure), and it is also possible to select any Tread and modify the tread Height individually.
However, what I would do is I would probably model such a Stair using multiple Stair elements.
By the way, a Stair is not associated to a Mesh and Gravity is not available as an option when placing Stairs.
Stairs should connect just two different points. If too steep tends to be ladder if too lowly tends to be ramp. Depending on inclination the structure changes too, rarely you can find steep concrete stairs and if you do they mostly have an inset at the riser to accommodate for short going, but you can find steep steel stairs with stringers or central beam.
Between the normal stair lower inclination range limit and the ramp, must be a range of values that can be solved with the combination of normal stair-landing or stepped landing or ramp- and stair again, where the user will be able to adjust the position of the landing.
Finally for very lowly grades, ramp or stepped landing should be incorporated.
The reference line of structure should connect the lower point of the first riser with the furthest end of the last tread.
I think this would make input very simple.
Just define the run you want, the algorithm will decide structures for each segment, in edit mode you will be able to change kind of structure if it fits, depending on inclination, (eg ramp and stepped landing or if segment very steep you will not be able to have monolithic options).
This kind of stair tool would fit better with Archicad's simplicity, and would cover nearly every possible case.
