[TowerTalk] 4-Square over sloping terrain

I'm in the process of putting up a K1ZM style 4-Square for 160M meters.
(K1ZM is 4 inverted-Ls).   I measured the terrain elevation and was
surprised to learn that the slope was greater than I had envisioned.   One
end will be almost 12 feet above the opposite end with the other 2 ends both
around 6 feet above the lowest end - works out to around a 5% slope.   I
have modeled this with AO and it does not seem to have much effect but not
sure if modeling is to be trusted...  I am looking for anyone with results
from putting a 4-square up on sloping ground.    K4SQR's literature
emphasizes the importance of keeping the feedpoints within a foot of each
other in height - the only way I can do this is to elevate 3 of the
verticals and deal with a mess of wire through a wooded lot and in view of
the house...   Again, I would appreciate hearing from anyone who has tried a
4-SQ on a sloping lot...   Thanks
