Ramp Vignette Solution and Question from NCARB solution

[SLOmustang713]

This is my ramp vignette solution for BDCS. I have taken this exam before and I failed the Ramp and Roof vignettes (ramp, I know I must have done incorrectly, and the Roof I didn't finish). So anything at all that could be incorrect please comment.

My question regarding the NCARB solution:
In their the solution, the stair appears to be 5'-0" wide. But this appears to be incorrect? Several folks have solved their vignette showing a 5'-0" sketch circle. I am using ARE Advisors Vignette Guides and those say it needs to be a 5'-0" by 5'-0" square essentially (if your going with your 5'-0" wide for your stair). When using the code in real life (I know this is NCARB-land) but I can't reduce my egress width from any point, and I follow the 5'-0" square. Which is correct, the circle clearance or the actual clearance?
So have also shown a 90 degree bend in their railing. Is that a possible solution that won't fail?

Thank you!

Width cannot reduce in direction of egress. What you have shown (min allowable stair width) is the best approach. If you had used a 5' stair, the distance from the end of the west rail to the north wall would have to be no less than the overall stair width.

So have also shown a 90 degree bend in their railing. Is that a possible solution that won't fail?

That is a possible solution.
