[CQ-Contest] 2000-2001 UBN Analysis (longish)

USA Contesters,

I've always been interested in how top USA contesters compare in terms of
accuracy and have wanted to do some sort of analysis. Given the fairly
dramatic shuffle in ranking between the claimed scores and final results for
CQWW CW 2000, I thought such an analysis would be useful to everyone.

Below is the output from a spreadsheet showing claimed scores and final
scores for the top 20 USA ops in CQWW CW 2000 and  ARRL DX CW 2001 (there
was some shuffling below the top ten in both contests and if I hadn't gone
down to the second ten my score wouldn't be included!) I can view this data
when I expand my e-mail window to full screen. If you can't, maybe turning
off word wrap will help. Otherwise, you should be able to copy the text to a
text processor and get rid of the extra newlines. If anyone would like to
post this data on the web, I'd be happy to supply the Excel spreadsheet.

It's hard for me to fully analyze this data because I'm not exactly sure
about the rules used by CQ and ARRL for UBN checking. My recollection is
that CQ imposes a three QSO penalty for a BAD call and ARRL does not. My
CQWW UBN reports seems to indicate that CQ just removes one QSO when it's
NIL. I'm not sure what ARRL does. I guess this would lead to the difference
in average QSO error percentage being less than 3x between the two contests
(it's less than 2x). Unfortunately, I don't think it's possible to draw any
conclusions about whether the CQ or ARRL rules make a difference in relative
standings. There aren't enough common calls between the two contests and the
sample is too small (some ops did relatively better in one contest than the
other, which could be due to a lot other factors.) It would be interesting
to do a long-term analysis across several years of contesting, although
changes in op efficiency would make that difficult.

The average score penalty is much higher in CQWW, but that's probably due to
the three-QSO penalty and the fact that you're much more likely to lose a
mult in that contest -- just look at the absolute number of mults lost
between the two contests. That's probably because in CQWW there are more
mults to lose and more rare mults.

I'd be very interested in any other observations, especially from the old
hands.

I did this partly because I was bummed out by my UBN performance in ARRL DX
CW. I was the dunce in that contest -- I had the highest error rate in the
top 20, dropped more spots than anyone else, and missed what would have been
my first top ten finish in a major contest from home. I was below average in
CQWW, too. The lesson is -- accuracy counts! K1AR has already made wise and
humble observations on that. I'm sure he feels worse than I do, but he's got
more plaques and top ten certificates on the wall than I do (XX to zero, I
believe.) I'm not at all against log checking -- I think it's great and
should be as tough as they can make it. The three QSO penalty is probably
irrelevant as long as it's applied uniformly to all ops. It does put a
premium on copying calls correctly, which is a good thing. Perhaps there
should be some incentive to copy the zone correctly, but let's not talk
about that ;-)

I only wish that ARRL would let us access the actual UBN report like CQ
does. I'm planning on comparing the CQWW report to my log to figure out my
pattern. I've already seen that transposition of 7 and 8, B and D, etc. is a
problem. I'll be looking at my '98, '99 and '00 reports to see if there are
times when I'm more likely to copy badly. I'm especially interested in why
my UBN percentage increased so much in 2000. It was 7.3% in '98, 4.6% '98
and 9.5% in 2000. I think it's because I crossed the 40 hour boundary and
fatigue played a bigger role, but I won't know until I look at the logs.
Does anyone else have a pattern like this? Were UBNs generally worse in
2000? If so, was that due to different UBN rules, propagation conditions,
new DX ops, or what?

I'd like to congratulate the ops who turned in UBN performances that were
nothing short of stunning. Under 5% in CQWW and under 1% in ARRL DX is
fantastic. As badly as I feel about my own performance, I want to recognize
their acheivement. I'm hoping to join that crowd and my attitude about log
checking is that it provides an incentive and opportunity for me to become a
better contest operator. Bring it on!

Here's the data:
