Yes... but didn't quite get what you did
What I understood is that you solved by using the finish stair twice, the second one used as "structural" and tread and riser parameters modified. Is this correct?
I used the stair without finishing as structural element, another stair with the finishing only as finishing element.
The sttuctural one is moved 30mm forward and 50cm down in order to be correct. Then I "play" with connection at the slab of the upper level where the structural rider is usually 50mm shorter, and with the connection at bottom where the structural riser is usually 50mm higher
This approach is generally easy and smooth for structural stair. Only in certain cases it is a bit complicated and you have to play with more parameters but I've been always capable to get the correct structural stair.
