Groups=Sections?
Hi Al!
Yep, of course everything depends upon about how one considers a 'group or section'; imo a group is any sequence of events getting the same properties belonging to the most possible restricted category.
Of course we can hope to be right for the almost entire lenght of the shoe, at the same time fearing that a large number of opposite 'heterogeneous' spots denying steady groups will come out sooner or later at a given shoe.
Most of the times, a shoe won't present steady long detectable spots and of course it won't present steady unguessable spots either.
But you know very well what I'm talking about.

as.
