  During the last two decades, in statistical process monitoring plentiful new
methods appeared with synthetic-type control charts being a prominent
constituent. These charts became popular designs for several reasons. The two
most important ones are simplicity and proclaimed excellent change point
detection performance. Whereas there is no doubt about the former, we deal here
with the latter. We will demonstrate that their performance is questionable.
Expanding on some previous skeptical articles we want to critically reflect
upon recently developed variants of synthetic-type charts in order to emphasize
that there is little reason to apply and to push this special class of control
charts.
