[Dx4win] VK5 DX Zones

[Alan Zack]

How does DX4WIN determine DX Zones? By the country list? I have the
latest country list in my DX4WIN
I just received my 2021 DX Marathon UBN results back and I got dinged
for entering VK5DOC for Z29. The VK5DOC qrz.com page does not show
what zone he is in. When I logged him in my DX4WIN log it was entered
as Z29, not Z30. The QSO is confirmed with LoTW. It shows him in Z29,
not Z30.
 
When I asked John K9EL, the contest manager, why I was dinged for a
wrong entry for Z29 here was his reply:
I also use DX4Win and if I enter VK5DOC, it says Zone 30.
I have never heard that any VK5 stations can be in Zone 29.  I have
been doing this contest since 2008.
 
John may very well be right but why would my version of DX4WIN show
Z29 and his show Z30? I only have one entry for VK5DOC on 07/03/2021.
In my log for Z29 I have many VK6, VK8, and VK9 stations but only one
VK5, the VK5DOC shows as Z29.
 
It is a mystery to me.
