Re-entries and Retouches are considered to be Constant Plate Varieties (CPVs), so we do not need to ask "Is It Constant?". These CPVs are not a part of this effort.
Guide dots and Guidelines, similarly, are constant and will not be included.
Dots which appear in areas where guide dots are not normally found will be included.
Lines which are not clearly guide lines are included.
Many of the stamps shown are not likely to be determined to be constant.
The darker stamp shades - green especially - may look black in the site images. Users trying to match stamps from their collections should not find this problematic.
