Positioning of the Spickeltritt on a 90° spiral staircase

For our planned flight staircase, we are currently looking for a compromise between walkability and space requirements. Due to limitations in the x and y directions, a step edge results exactly on the axis of symmetry of the 90° turn (shifting 4 steps each before and after).

As a result, the triangular step is "omitted," which, in many staircases, lies exactly symmetrical in the turn, i.e., is framed by both stringers. Compared to our design, the steps are shifted by about half a tread width.

Can someone tell me the reason for this approach regarding the triangular step? Is it solely for aesthetic reasons? Or are staircases with symmetrical triangular steps (seemingly or actually) easier to walk on? I wouldn’t know why.

A few details about our staircase:
Floor height: 325 cm
Number of risers: 18
Tread width: 26.9 cm
Riser height: 18.06 cm
Width: 183 cm
Length: 370 cm
Design: Concrete staircase, folded plate look

This eliminates the "Spickeltritt,"

... which is not part of the average academic’s vocabulary. I myself had to google it first to find out that it is not dance instructors or choreographers but stair builders who learn this term in their training. I am myself “not neurotypical” and numerophilic, but I absolutely do not know anyone who thinks about such special aspects when using stairs. As a construction consultant with over forty years of experience in the house building field, I have never come across this term. That your stairway should be the first with this “chromosome defect” I can hardly imagine.

Thank you. The only practical "benefit" of a symmetrical winder step that I can think of would be more standing space in the corner for flower vases or similar. Then this winder step requirement in the staircase specification will be postponed for the time being...
