[Bioc-devel] Package download stats inflated? (specifically cummeRbund)

Hi Bioc-devel,
I am the package maintainer for the cummeRbund package and since I'm  
not exactly sure to whom I should ask this question, I decided to post  
to the bioc-devel list.

Since this is my first Bioc package I have been keenly interested in  
the download stats that are tracked and visible on the Bioconductor  
website, here:


Specifically, I'm noticing that the number of downloads for the  
cummeRbund package seems to far outpace the number of unique IP  
addresses downloading the package:


For a few months there was a mean of between 10-20 downloads per  
unique IP address, and for the current month this is on track to be  
about 36 downloads/IP (and looks to be about 8.7% of the total BioC  
packages downloaded this month so far).  Looking around at several  
other packages, this does not seem to be the case as most of the  
packages in the top 30 list have a ratio of about 1.8-3 downloads / IP.

As ecstatic as these numbers make me, I'm certain that there is some  
underlying reason for this inflation that is not being appropriately  
represented here, but without anything else to go on, I'm not really  
sure where this is coming from.  I would obviously like to have an  
honest representation of the number of downloads for my package, and I  
was hoping that someone with access to these data could help me track  
down the cause of this download inflation (unless these numbers are a  
true representation of the downloads, and then I would also very much  
like to find out more demographics if possible as well).

Any and all advice or information is appreciated!  Thanks to all, and  
a special thanks to everyone that helps to keep BioC such an amazing  
project.  I have enjoyed the benefits of bioconductor for the past 5+  
years and I'm very happy that I can finally start to contribute back  
to this wonderful project.  (Also, I look forward to meeting some of  
you at BioC 2012 this year!)

Thanks in advance!
