THE GROUTLINE
For the time being, the GIN method
can apparently claim for itself to be a
“new” or even the “newest” one.
In front of these facts, it could be in-
teresting to hear on the basis of which
considerations the GIN method has
been defined as “regressive” or “ret-
rogressive”. This is independent of the
fact that the method is “disturbing” a
number of people and this for unknown
reasons.
