Note: I liked Bob's reply, which came I as I was writing this. I doubt I
can do any better, and I have the same problems he does with the pictures.
I can't see into the cells. I agree with Bob on all points, but my
perspective is perhaps a little different, not being strictly a production
beekeeper.
Continuing...
I also used the word, "too". What constitutes, "too", depends on the
circumstances. I also wrote the quoted material in the context that
categorical statements are often made that seem to say a poor pattern
necessarily means a poor or failing queen. Actually, usually, in practice,
for most intents and purposes it does. There are, however, exceptions.

That is not what I said, or even implied.
What I did say is that one must interpret a brood pattern, and not just
reflexively assume that a spotty pattern is a queen problem. Further
observations should be made before automatically replacing a queen after
looking at one comb.
Brood patterns reflect many things: season, nectar and pollen flow
conditions, toxic food, disease, queen condition, queen age, queen quality,
inbreeding, the condition of the nurse bees, beekeeper screw-ups, effects of
dusting, heavy incoming pollen and nectar usurping brood cells, etc., etc.
Brood patterns can also be inherited from a previous queen, or be due to the
condition of a particular comb, or the result of larvae being removed due to
disease, corrosion products in the wire or wax, etc., etc.
Additionally, some beekeepers may be keeping an inbred queen for breeding
purposes. Of course anyone advanced enough to be doing so does not need me
to tell them about brood patterns, but I mention that so as not to be
misunderstood.

Like what? Seems to me that if one ignores it, one does so with an
understanding of why so the consequences should all have been considered.
If not, Bob's advice should prevail, but, Bob's goals and your goals are
very different, as are mine.
Sometimes a comb with a poor pattern can be right next to one with a
surprisingly perfect pattern.

I took a look and can see a few obvious things, like poisoned brood along
the wires, sagged comb, individual cells empty with the six adjacent cells
also removed (!), pollen packed into cells among the brood, signs of an
apparently older queen, but without a context (season, hive size, etc.), and
having limited time -- and not knowing where you are going with this -- I
have not looked deeper. There are other things, and I only glanced at the
first few. The pictures are a bit small and hard to manipulate.
OK. Ah-ha!
I think I have it figured out now, and can see this is an exercise that is
going to take some time. I now see that you have two shots of each frame,
taken at some unspecified time interval. It looks as if you have done a
pinprick test on each at the points marked.
I assume that our assignment is to assess the general brood pattern of each
and relate it to the results of the pinprick test.
Correct?
We are having our Canadian Thanksgiving dinner today and have company, so my
further comments will have to wait a bit. I'll have to figure a way to see
larger pictures side-by side than are apparent on this netbook.
At any rate, thanks for this. I look forward to further comments from
others and having a more detailed look on a large monitor with more spare
time.
This should be good.
