Hello again everyone,
I've done some more looking at data, but I'm feeling a little limited by the
data that is easily available. I'm looking at the CQWW Records instead of
results simply because they are readily available in a format I can import
to Excel easily to massage the data. I'd love to do this same kind of
analysis with the overall results from several years of contests - that data
just is not readily available to me.
With that limitation in mind, what I think I'm finding (with purely the
data, no other information) is that serious ops who have really good skills
can do better with assistance. However, it seems that when an entrant is
operating "more casually" they tend to operate in the assisted category, and
thus have lower scores not because they are assisted, but rather because
they are operating more casually.
For example, let's look at VK5GN and D4B SSB records for SOAB and SOAB(A).
Both records were set within a couple of years of each other, with the
larger score coming later in the solar cycle decline. The propigation
conditions would have been similar, although I do concede that specific
solar weather conditions (flares) are not take into consideration. I've
been looking for a source of historical Solar Flux, Sunsupt Number,
Planateray A &K indices, but have not found anything comprehensive. I have
found the following site (http://www.solen.info/solar/old_reports/) but it
only has data back to 2004. Anybody know if a good source for historical
Solar Weather data?
Category Call Score QSO's Zones Countries Year Zone A VK5GN 3,709,900
2928 127 333 99 30 AA VK5GN 1,844,180 1841 108 238 97 30 A D4B(4L5A)

In the example above, there is the same operator, operating the same
station. Now, within two years there could have been lots of station and/or
operator improvements, however the score differences are pretty significant.
Here's a few comparisons that go the other way:

5H3HK(JE3MAS) 5,786,933 4445 119 342 04 37
These all seem like pretty serious operations, from obviously competitive
stations. In these cases assistance seems to have made the difference.
Looking at the following 12 "close races" (which I defined as generally
within 1meg points of each other) in the CQWW SSB records, the assisted
scores came out on top in 5 cases, or 42% of the time. Again, this analysis
does not take into account other factors such as solar weather.

My general "feeling" (meaning not directly data driven in any way) is that
operators tend to select the assisted class when they are operating "more
casually". However, when an operator is doing a full tilt operation,
assistance does make a difference in the total possible multipliers AND
overall score.
I also draw the opinion that operating skills, operator dedication and
station design are much more important than assistance in achieving a good
overall score.
In the end, I still dont' think that SOAB entries (assited or not) will ever
rival MM mult totals - and if they do, their q totals will have suffered
significantly. Records will continue to fall, maybe because of cheating (I
hope not), or maybe because of better equipment and operators. Either way,
it's all just a very interesting game.
As before, this is posted to my blog as well (http://wp.me/pdJH2-1H), in
case the tables don't format right in your e-mail.
