	Agree, with a very small quibble..  But isn't the expression using the
capacitance ratio more instructive way to look what actually happens? 
As you point out, the process starts with energy stored in the primary
capacitor, and the maximum peak voltage in the secondary occurs when all
of the energy from the primary capacitor is stored in the secondary
capacitance.
