no number is in fact better than wrong numbers backed by nothing beause 
they lead in wrong conclusions - your 122/133 numbers could in reality 
also be 1000 users installed them from mirrors and your calculation is 
the best example for wrong assumptions

you don't have 132 downloads because 132 mirrors
in fact you have *zero* - mirrors are done with rsync
