Interesting point Jose.
While this is certainly true in the D4B/ZD8Z/P40E case;
I take the opposite view in the USA case.

During CQWW or ARRL DX the maximum rate is ~200/hr and that is only once or
twice on Saturday morning.
The next few hours might yield 150 at most, even at superstations. The
average rate is 120 during peak hours and way down on Sunday.

If you are working only 2 or 3 stations maximum in a minute; that leaves
~30sec of CQing per minute.
I submit it is an advantage to have a longer call!
KQ2M will be easier to find than K5ZD or N2NT. He will have more air time,
and someone might tune by a shorter call with pauses between.
In USA we don't rely on being spotted on packet, it is more band presence.
Also, that is why SO2R becomes more important and you get large second radio
totals, but that is another subject.

To your point, I found it easier to use VY2NT than VY2ZM this year in CQWW.
The rates were much higher, and a shorter call seemed to help. The rates
were higher which caused me to ID less frequently, but I had a different
solution. I would ID very fast. I'm not sure it is the best solution since
many copied UY2NT. But at least I tried :)

That being said, I picked my call originally for the very reason you stated.
I was interested in a short call for the sprint.
In that case it is a big advantage.

73 and ThanKs for the great input.
