For comparison, using a "not-WPX" call:

W9WI was spotted ten times in somewhat less than 36 hours. I ended up
with roughly 1,250 QSOs. (including dupes)

The proportion was similar in my log. (considering the small sample
size) Only three of the calls that spotted me were in my log. Two
(NJ1F and RF4R) were worked at the same time as they spotted me. (RF4R
spotted me two more times later in the contest) The third (9A6XX)
spotted me several hours after we worked.
None of the spotters were in Tennessee. RF4R was the only one to spot
me more than once. I can assure readers K5NZ wasn't favoring Texans as
he was one of the W's who spotted me...

Average "pre-spot" was 9.0, "post-spot" was 8.2 for a *decrease* of 0.8
QSOs or roughly 9%.

In my case there seems to be no correlation between rate change and
time. It is interesting to note that *every* time I was spotted by a W,
my rate declined; with one exception, every time I was spotted by a DX
operator, my rate increased.
I have no idea what conclusion to draw from that!

While more analysis would be necessary I do tend to concur.
Which certainly disagrees with advice I gave N4ZZ (who luckily ignored
it!) before the contest...
