It can't be that, as TuKa has negative values!
My guess is that it shows net changes in network subscribership as
percentages of net change in total subscribership, which is not very
useful at all. Imagine what happens to the figures as total growth
slows or turns negative.
What I think we're seeing here is that an attractive offer from (for
example) AU can gain it lots of subscribers, increasing total growth
for that month and thus reducing percentages for all the others (since
TuKa's growth is negative, it 'increases' towards zero).
A graph showing actual numbers of subscribers lost/gained each month
for each network would be more useful in gauging which networks are
going where.
