[CQ-Contest] LR vs LPL

There has to be more to it than the absolute distance to Europe,
and having sunset 20-30 mins earlier on the coast. I remember
when I lived in NH, about 1 mile from the ocean, EU was LOUD on
my attic dipole - frequently louder than here in eastern PA (abt 60
miles from the ocean) with my TH7 stack.
Also, a few years ago, I operated CQWW CW from K8AZ (only abt
60 miles or so west of K3LR, I believe), and commented to one of
the guys, "I can't get a good run going on 40, only 6-70/hour." His
answer was "welcome to 8-land!"

On the other hand, the Gs may be the last signals heard on 40,
being further west, but the southern EUs are frequently louder (and
they're not all running Italian "300W" amps, are they?). If that's the
case, why is it advantageous to be in W1 vs. W4?

Part of the answer is likely to be how close the signal passes over
the pole/auroral zone. Other ideas?
