 There's no good explanation yet, but I started looking into that in
 #16555.

 > Regarding the [https://metrics.torproject.org/userstats-combined-
 data.html data page]:
 > The variables 'country', 'total', 'transport' used in the formulas
 should be renamed, i.e., have other names than the columns, and defined.
 The cvs columns 'country' and 'transport' contain strings and 'total' is
 not defined.

 Right, how about these definitions?

 '''low:''' Lower bound of users by country and transport, calculated as
 '''max(0, C + T - S)''': if the number of users from a given country
 '''C''' and using a given transport '''T''' exceeds the total number of
 users from all countries and transports '''S''', there must be users from
 that country and transport.  And if that is not the case, 0 is the lower
 limit.

 '''high:''' Upper bound of users by country and transport, calculated as
 '''min(C, T)''': there cannot be more users by country and transport than
 there are users by either of the two numbers.

 Cool!
