This is pretty much true until one arrives at the plateau area above the
knee of the load curve. With a resoant-choke/C filter, the needed C is
much smaller than would be the case with a C-filter. . . . Also,
when glitch time arrives, more Joules is not better.

- The waveform is a bit more complex than simply 2x the mains frequency.
There seems to be a bit more to it than looking like a bigger choke.
