I can't comment on that, since I don't have reliable data, but simply asked,
what about the other plain? And it also is much easier to have a slotted pipe
type receptacle, with a steel tape spring surrounding it to guarantee,
constant, long-term contact pressure for a round, mechanically sound, 5mm pin,
which gives solid, equal contact all around its circumference.

I think it has a good reason that the later added third ground pin for the US
system isn't of flat spade shape anymore, but strangely a round one now with,
who would have thought it, 5mm like in the Schuko system as well ;-)

All three pins on the other end of an IEC power cord are flat blades.
