Many thanks for the responses to everyone.
I don't think, it's simply the propagation.
That's why I was asking my question.
The target area of the contest is NA.
Now, I checked RBN spotters in NA only.
I had a look at the hourly QSO distribution on
https://contestonlinescore.com/.
With shifts, of course, but they are very similar.
ARRL DX is a typical contest where CQing dominates, especially in single
band categories.
So it would be reasonable that the number of RBN spots is
similar/correlating for each station.
During the first four hours the contest the QSO numbers were so (according
to contestonlinescore.com):
HG5E: 181 (it's me)
HG0Y: 138
UA9YBA: 216
In those 4 hours the numbers of RBN spots in NA were so:
HG5E: 403
HG0Y: 95
UA9YBA: 3
TM4W: 127
UA9YBA made the most QSO but got only 3 RBN spots from NA.
During the entire 48h period the figures of NA RBN spotters:
HG5E: 4329
HG0Y: 3383
UA9YBA: 61
TM4W: 4922
So, I'm just curious, why UA9YBA got only 61 RBN spots from NA, while the
others around 4000?
The number of made QSOs are between 900 and 1100 by each station.

Dear Experts,
I created a quick statistics sheet on RBN figures of the ARRL DX CW
contest.
I took 4 SOSB 20M stations: HG0Y, HG5E, TM4W and UA9YBA.
Here is how many times they were spotted by RBN in North America:
HG0Y: 14236
HG5E: 16648
TM4W: 16223
UA9YBA: 4918
According to 3830scores.com and contestonlinescore.com pages these are
the QSO numbers:
HG0Y: 1005
HG5E: 902
TM4W: 1139
UA9YBA: 967
My question: how could it be that three stations were spotted by RBN three
times more than UA9YBA?
I listened to UA9YBA at the end of the contest and his CQ was absolutely
correct: "CQ UA9YBA UA9YBA TEST".
