I have belatedly accessed your Google document and query some of the 
interpretation.

It is unfortunate that it relates to August since I cannot recall what I 
was doing then and that is prime holiday season when not much happens. 
If you had chosen the week in July before the submission window closed 
for IETF108 you might have got much larger figures.

However, I wonder if I have been missed entirely (perhaps along with 
many others).  Being a small business I am behind an ISP-provided NAPT. 
  I could be sharing that NAPT with others.  I suspect that most often I 
get the same IPv4 IP address but perhaps a different port.  I am likely 
sharing the reverse DNS name with others, perhaps hundreds:-)  Thus I 
know that location tracking websites think that I am in Preston, UK, 
whereas in fact I am 50 miles away; IP-derived data can be plain wrong 
so when you conflate on the basis of reverse DNS, you could be missing a 
lot of small users and only counting the Microsoft or Cisco or such like 
and even then you could be missing a number of employees of such an 
organisation with a unique reverse DNS.

I do use the same ADSL modem for FTP for RFC and FTP for I-D (and HTTPS 
access to data-tracker) and will likely download an RFC or two most 
weeks and an I-D or two most working days, three or more days a week but 
I do use a different application for FTP RFC and FTP I-D.  So I am 
multiple download most working days from a UK ISP.  I struggle to see 
that in your data and suspect that you are missing many, perhaps most usage.
