You have to know both methods because many stairs require a midspan stringer which is always notched. You first make the tool loose by loosening up the screws. And the calculator figures out the spacing for the lengths as before: $$A_1 = Rise × sin⁡\,\alpha_2 = 7.06\,in × sin\,55.86^o = 5.84\,in$$, $$A_2 = Stringer\,Width – A_1 = 12\,in – 5.84\,in = 6.16\,in$$, $$C_2 = \sqrt{Run^2 – {A_1}^2} = \sqrt{(10.41\,in)^2 – (5.84\,in)^2} = 8.62\,in$$, $$C_3 = A_1 × tan\,⁡\alpha_2 = 5.84\,in × tan\,55.86^o = 8.62\,in$$, $$B_1 = \sqrt{Rise^2 – {A_1}^2} = \sqrt{(7.06\,in)^2- (5.84\,in)^2} = 3.96\,in$$, $$B_2 = A_2 × tan⁡\,⁡\alpha_1 = 6.16\,in × tan⁡\,34.14^o = 4.17\,in$$, $$B_3 = (Rise -Tread\,Thickness) × cos⁡\,⁡\alpha_2 = (7.06\,in – 2\,in) × cos\,55.86^o = 2.84\,in$$, $$A_3 = (Rise – Tread⁡\,Thickness) × cos⁡⁡\,⁡\alpha_1 = (7.06⁡\,in – 2⁡\,in) × cos⁡⁡\,34.14^o = 4.19⁡\,in$$, $$A_4 = Stringer\,Width – A_3 = 12\,in – 4.19\,in = 7.81\,in$$, $$C_4 = A_4 × tan\,\alpha_2 = 7.81\,in × tan⁡\,55.86^o = 11.52\,in$$.
