If used extensively with good data, will tell us the relative
effectiveness of mounting heights. With that information, we can make
more intelligent decisions about what to do with what our real estate,
budget, and other capabilities allow.
In my case, I learned that 120 ft was near optimum for EU, my most
difficult direction, that a few more tower sections were not better, and
that to get better, I'd need to go to at least 300 ft! :)
I also learned that 20 ft at different location on my property was a
minor sweet spot for a small 10M yagi.
I spent close to a month on it. Neighbor K6XX, 4 miles up the ridge from
me, used it extensively in planning his antenna farm.

Speaking primarily as a ham radio DXer, constrained by county zoning limits, my take on
terrain modeling is, "What am I going to do about it?" Propagation prediction
is pretty much the same question.
