LOS and Cliff/Wall (vertically drawn) hexsides

[commissar1969]

In the illustration below, is there a LOS between R7 and P7? Why or why not?

 

[Robin Reeve]

The wall is a hillside wall, and has no impact on LOS.

B9.61 LOS: A Hillside wall/hedge (including both its depiction and its associated hexside; 9.1) is ignored (even along a Continuous Slope) when determining whether or not a LOS exists between units whose elevations differ by ≥ one full level

The cliff depiction doesn't block LOS.

B11.2 The serrated edge of a cliff is no more of an obstacle to LOS traced along that hexside than the elevation level it separates from the higher hill hex.

So I think that LOS exists between R7 and P7.
