There is ambiguity in our definition of attributes like
impressionsCompletedCurrentCopy and currentCopyNumber in terms of how t=
o
synchronize them. Basically, the first is a trailing edge function, the=
second
is leading edge. This results in undefined states between the last impr=
ession
of a copy and the first impression of the next copy.
I would like to rename currentCopyNumber to sheetCompleteCopyNumber and=
make
sure the definition clearly points out that all "currentCopy" attribute=
s
trigger off the SAME event, which is basically a sheet stacking. The
sheetCompleteCopyNumber should start with a value of -1 or -2 to indica=
te it
has no meaning until at least one sheet has stacked. When the sheet sta=
cks then
the values impressionsCompletedCurrentCopy =3D 2 and sheetCompleteCopyN=
umber =3D 1
make sense. The sheetCompleteCopyNumber should always refer to the copy=
number
of the last sheet stacked and never point forward to some future copy w=
hich is
being worked on.
