Could it be that the larger coils were inefficient due to other factors other
than "inherent" inefficiency.  For instance the larger coils may have been
using ballasts that were saturating, transformers that were saturating, gaps
that were not quenching well, etc. It seems to me that large coils would not
be inherently less efficient.  True, there will be greater losses in the
absolute sense, but I wouldn't expect the proportional losses to be higher in
the large coils.  Do you have an explanation for the lower efficiencies
you've seen in the large coils?
