LOS Question from Hill

[plloyd1010]

Philippe, I presume you are referring to the effect of my crest rule. The hex indicated by the red and those of the green arrows would be out of LOS of hex 0812. That is because, extending the LOS path behind 0812, there is no higher terrain of that hill behind 0812, and there are fewer 20-meter hexes (0) behind 0812 than there are in front of it(1).

The reality is that one cannot see anything below the hill when looking across the top.
