The numbers -only- show the effect of remapping, currently the far
larger effect is acceptance of the CTs by mappers who haven't done that
up to now. Around 0.1 to 0.2 % per month (depending on the object
category). In other words, using just as silly extrapolations as you do,
we would have 100% of everything anyway in roughly two years if we
simply just let things carry on as they are now (which is not the
intention).

It seems as if the community is not that motivated
to re-map all those evil CC-BY-SA data that
sneeked into into the future OdBL fork.
In this pace we need more then 7 years to fix it.
Common CT-OSM members, start mapping all
that misleading non-CT data ! Someone
may use it in a routeplanner and drive
by accident into a CC-BY-SA road, and
who knows what happens then.

[Apologies in advance for the HTML formatting]
As you may have noticed, the sysadmins were kind enough to generate a
new full history dump over the last couple of days. Besides generating
new numbers for odbl.poole.ch (which will take some time for the full
set), I was mainly interested in seeing how large the effect of
(intentional or not) remapping has been over the last three months.
As can be seen from the following numbers, while the effect is not
particularly large (nobody has really called for aggressive remapping
yet) it is quite noticeable.

Note: both set of numbers (from the 19th of June and the 19th of
September) use the same licensing state data from the 22nd of
September. The "Mappers" row reflect the change in the number of
mappers that created objects that are still visible in the database.
