We had been through this before in alt.engineering.electrical. Those
who once strongly advocated 'point of use' protectors (ie ex-GE
employees) have backed off that recommendation. One example is an IEEE
paper by them about an "Upside Down House". Francois Martzloff and
Thomas Key in 1994 wrote in "Surging the Upside-Down House: Looking
into Upsetting Reference Voltages" :


Conclusion:
1) Quantitative measurements in the Upside-Down house clearly
show objectionable difference in reference voltages. These occur
even when or perhaps because, surge protective devices are
present at the point of connection of appliances.


This is exactly what a multiport plug-in point-of-use surge protective
device protects against. These are called Surge Reference Equalizers by
the IEEE. Another paper specifically about SREs is

This paper is currently available from the NIST in a collection with a
forward by your good buddy François Martzloff (who was an author of this
paper).

I have provided links to an IEEE paper and and 2 NIST papers, all
current, that recommend plug in surge protectors. In previous threads
(and this one) I have not seen any links supporting your view. Its you
against the IEEE and NIST (and a lot of other people).
