As far as this aspect of the scale is concerned, let me add it is really no
indication of any bias here. It's just that the skies are that good, and most
commonly around 5, 6, 7. An 8, 9 or 10 is appropriately rare, amd the low
scores are just thrown out, that is, there is no report because no observing
was done or they just stayed home. I'm sure if any of us got out on the ice
before a bank of Olympic ice skating judges, there would be a lot of 1, 2 and
3 ratings pop up. I've seen these low seeing ratings when observing doubles,
and was astonished at how horrible everything looked, when the night before
the same object was a beautiful sight. I would think my telescope got horribly
ruined somehow, but it was only 5 arcsec seeing doing it (or I left the bag on
the secondary but that's a different problem). Anyway it was nothing to write
home about.

Tom sed:
One thing I have noticed about the transparency ratings is that they don't
seem to use the full scale. Ratings below 6 or above 8 are very uncommon.
It's sort of like figure skating scores in the Olympics. Perform the routine
to perfection like a programmed robot, and receive a 9.92 out of 10; fall on
your butt several times and stumble through the routine, and receive a 9.78.
