Actually, the number of encrypted messages that I originally posted was
incorrect.  The real number is 641.  I replied to my original post and
posted the correct numbers.  You can find them at this link

No Yahoo notifications were counted in any of the numbers that I posted,
since none of those messages were from someone on or joining the list.
But all other messages were counted, including my initial post of my
public key.

36 is correct. I took note of every NETMK (Not Encrypted To My Key)
message, who was complaining, and who hadn't encrypted.

Also note that 36 NETMK messages does not mean 36 messages that weren't
encrypted to someone's key.  Sometimes a person had multiples messages
that he couldn't decrypt, and sometimes multiple people responded to the
same initial message with NETMK messages.

I agree with Hansen that this is seems almost like cherry picking, but I
will give it to you anyway. Six in the first week and four in the last week.

But before you say, "Ah ha," know that four of the first week's messages
were from a person that had successfully sent encrypted messages to me
prior in that same week.  Also two of the last week's were not due to
someone removing my key from his list of keys.  In both cases someone
else couldn't read the poster's message and the poster replied with a
message the NETMK complainer and I could read.

It's not that you need this much detail, but without it you might come
to incorrect conclusions about the causes of the messages that I
couldn't decrypt.

As for the proportion of unencrypted message, see the top of this message.

No one sent NETMK messages in the last week.  But if I deduct the 4
messages that I could not decrypt that were sent in the last week, then
the ratio of NETMK messages plus messages not encrypted me to all
messages is approximately 1 in 13.
