DAR BB33, Once More Into the Funnel!

[plloyd1010]

Here are examples for Presumed Crests. I also put this over on the What We Play Redux thread.
Refer the graphic:

1. A can see 1. LOS crosses 1 20-meter hex while the extension behind A crosses 3 20-meter hexes. (Number of hexes behind are greater in number than hexes in front.)
   
2. B cannot see 1. LOS crosses 2 20-meter hexes while the extension behind B crosses 1 20-meter hexes. (Hexes behind are less in number than hexes in front.)
   
3. C can see 2. Extension behind crosses higher elevation of same hill. (Higher elevation behind.)
   
4. D can see 3. LOS crosses 1 40-meter hex while the extension behind D crosses 1 40-meter hex. (Hexes in front are equal in number to hexes behind.)
   
5. E cannot see 3. LOS crosses 2 40-meter hexes while the extension behind E crosses 1 40-meter hex. (Hexes behind are less in number than hexes in front.)

Remember, LOS functions both ways, but the higher observer is used to determine validity.
