[CQ-Contest] IARU HQ stations - final results question

[SP5UAF]

Hello,

Thanks to ARRL we already know the top scores of Single-Op and
Multi-Op stations as well as complete results of HQ stations in the
IARU HF 2003.  
Well, we all know that usually final scores are reduced comparing to
claimed scores. No wonder, we all make mistakes receiving or typing
callsigns, serial numbers etc.  

But claimed and final scores can be surprising. Claimed scores were as
follows for IARU HF 2003 (top ten):
Call                 QSOs     Mult    hr  Score
                 CW     SSB
R7HQ                 16701     423        22,317,903
DA0HQ                19085     473    24  17,869,467
GB5HQ             6400  6487   448    24  17,074,624
TM0HQ             5873  6153   434    24  16,816,198
OL3HQ             5123  5677   428    24  15,807,324
SN0HQ             7809  7874   456    24  15,752,520
IU2HQ             5375  5633   443    24  13,300,189
YT0HQ             5648  5429   445    24  13,070,095
S50HQ             5054  4901   448    24  12,433,792
PA6HQ             4834  4540   406    24  11,646,110
SK9HQ             2234  1767   327    24   4,140,147

And we have the following final scores (top 13) from the ARRL page
(http://www.arrl.org/contests/results/2003/IARU.pdf) 
R7HQ            20,817,380
IUxHQ           17,824,836
DA0HQ           16,507,800
GB5HQ           15,705,914
TM0HQ           15,394,425
SN0HQ           14,483,480
EM5HQ           13,425,363
9A0HQ           13,085,082
YT0HQ           11,662,121
S50HQ           11,311,048
OL3HQ           11,254,590
OH2HQ           10,880,332
PA6HQ           10,689,448

It's a pity we do not know multiplier and points data details of the
final results. But we can see two big differences in claimed/final
scores.  

The first one is OL3HQ. Their claimed score was much bigger then the
final one. I think that they made a mistake in the claimed score.
Perhaps by mistake the "15" WAZ zone number was input in the log
instead of "28" (ITU zone). It could make such a difference in the
result.

The second situation is with IUxHQ. Final score is about 4,5 milion
points better to claimed score. Perhaps Italian HQ operators lost
about 2.000 contacts in their claimed score. I think such a difference
in the QSO number can produce about 4,5 mln points in the final score.
Maybe we will be able to see the complete data (QSOs, QSO points,
multiplier) soon after the complete results are published. But perhaps
in the meantime someone from the Italian HQ team can give us some
light in the subject.

Thanks in advance
