You can set the steps as floating steps to get the ones near the winders corrected. Also, the steps on the second flight were not straight.
I corrected this and your tread width is now 10″.
The winder steps can also be set to floating to adjust them independently from each other.
I see you did not work with a landing step but extend the stringer length beyond the last step 4 inches. So that flight is 104 inches. Is that correct?
