Yes. Nobody ever suggested  to use the "Installed" number as a
reference.

Well, not exactly, unless I misunderstood what you meant.
509363 - 80793 = 428570, while <old> shows 404082. I am not sure where
this discrepancy comes from, though. Ideas welcome.

Correct, but it should be noted that "some reason" actually means "the
number of people who (1) enabled popcon data sending in menu System >

at least once in the last 30 days, and (3) don't have /usr mounted with
noatime." (2) and (3) are  according to the popcon FAQ whose location I
gave in another mail yesterday.

Unless, of course, you want to argue that the popcon client application
is sending invalid data and/or the popcon server miscalculates the
numbers. If so, then I'm afraid you'll have to show proof for this
assumption.

For the second time, the computation method is explained in the
README.gz and FAQ.gz files in /usr/share/doc/popularity-contest

Above, you said with regards to Evolution, that "Old is just a
subtraction". We have seen that this is not exactly the case, but I
guess it is close enough for now.
What I don't understand is why the same method is unclear for you
regarding Thunderbird?
