Nice of Paul to also demo how we might edit the Alignment Design Criteria files themselves.
The video demos that Alignment Design Criteria in Civil 3D is another case where employing the exact start and end station values often create annoying calculation issues.
On a practical basis most jurisdictions in the US tend to require that the Design Speed actually changes before and after the start and end of curves and spirals.
If we take the time to set reasonable local Design Speeds when the Alignment is first created, we may get a jump on these details.
