Your SSTC results are truly fantastic and have progressed much
faster than I ever expected.   It makes sense that the losses are lower
than in a spark gap TC.  A good spark gap TC in the larger sizes can
sometimes approach

    spark length inches = 2*sqrt input watts

The 1.7* figure that I usually use is a good average figure for
efficient coils but since larger coils tend to be more efficient, they
can reach a higher coefficient figure.

Some 20A breakers can supply somewhat more than 20 amps for awhile.

I point all this out just to fill in the picture a little.
