I agree that Distance-Based scoring can't work, but while Distance-based 
ranking has some attractive features there are problems with that approach, too.

WRTC uses Distance-Based ranking to select teams to represent each geographical 
region of the world. That's a great way to level the playing field as far as 
propagation is concerned, but doesn't actually answer the question "Who is the 
best operator in the world?" We have to run the WRTC competition itself  to 
determine that (not a perfectly level playing field, but it's the best we have.)

The point is that while winning one's region may make a contester feel better, 
there will always be the question of how contesters compare across regions. Who 
is the best in the USA? Who is the best in the world? Even if the contest 
sponsor doesn't hand out USA and world trophies, the question will still be 
asked. And winners of W1 will tell themselves they're better than winners of 
W5, and winners of W5 will still envy the rates and scores of winners of W1.

Perhaps this is justified. Some will make the point that it takes a different 
skill set to win W1 than it does to win W5 -- higher rates, bigger pileups, 
more mults to find, etc. (similar to SO2R -- it gives you an advantage, but it 
takes a high degree of skill to exploit that advantage.) I suspect some in W1 
would mutter under their breath, "Yeah, you won W5 but you did it with 2500 Qs, 
350 mults and 5 million points while I did it with 4800 Qs, 450 mults and 10 
million points! Clearly, I'm the better op."

It gets worse if we look at it from a worldwide perspective. Can the winner of 
DL really compare with the winner of ZD8? What happens when the highest-scoring 
station in the world is the only competitor from an island entity? Would there 
be just a certificate for winning from ZD8 (against no competition) and no 
special recognition for beating everyone else in the world? I would have a hard 
time comparing myself as winner of W1 (if that were ever possible) against a 
winner from ZD8 who did 10,000 QSOs in 48 hours.

Awards are another consideration. I doubt that contest sponsors will be able to 
award plaques to regional winners, so do plaques go away? Some of us have 
drawers full of paper certificates and would like to compete for some hardware.

Finally, if we level the playing field for location, will there be a push to 
level it even further? Perhaps we could eliminate antenna and location 
disadvantages by rank stations according to HFTA figures of merit (tongue in 
cheek here.)

It's easy for me to say all this as a W1, and believe me I sympathize with 
contesters in other regions that don't have the propagation to EU that we do. 
But I don't believe Distance-Based scoring or ranking are the way to make them 
feel better.
