I have to say a resounding "hear hear" to that statement. I have
done some calcs during the coil charting exercise using optimistic
figures for Vp and BPS and then comparing those with stated input
power. The huge variation in some of the coils suggests that in many
cases either (a) input power was measured incorrectly, or (b) not
measured at all. But some coils definitely do a lot better than
others. I hope to have a condensation of some of these figures when
