No, there isn't, that's misleading.

#!/bin/bash
wget --quiet 
"http://maemo.org/download-stats/fetch.php?unixname=$1&os=Maemo5" -O -|\
awk -F'[' '/^ *var d/{for(x=1;x<NF;x++){split($x,a,",");
total+=a[2]}}END{print total}'

(also at http://www.mauve.plus.com/count-downloads)

This says - for ecoach - 105529.
http://maemo.org/download-stats/index.php?unixname=ecoach&os=Maemo5&repo=extras 
is  the page which it pulls this info from.

http://maemo.org/packages/view/ecoach/ says 108000

But.

http://maemo.org/packages/view/ecoach/ - gives several dates, if you 
look at the package events, and glance at the graph, you can see that 
both the 'download-stats', and the 'maemo.org/packages/view' page must 
be counting downloads from extras-devel and testing too.

For some preliminary analysis that I did for fmms - as many users have 
testing enabled as extras.

The download number is also misleading - as it's really 'total downloads 
and updates'.

ecoaches headline number is 100K.
In reality, it seems likely that the real number of users is more like 10k.

(integrate the size of the spike after each package event, and you can 
see how many updated. If you look at the shape of this when there are no 
external events, then you can decipher stuff.

For example - a upload of a fresh version to testing - if over the next 
5 days, there are 5K downloads, and then 12 days later when it's pushed 
to extras - there are 3K - then it's probably reasonable to assume there 
are around 5000 users with extras-devel enabled, and 3000, with extras only.
