John one problem with using a watts per foot of spark rating is that 
the length of spark is also frequency dependant. The higher the 
frequency the shorter the spark for the same given power level.
There is also the problem of quality of spark ie. long thin spark as 
aposed to shorter fatter spark, generaly higher voltage and 
less current produces the long thin spark and the short fat sparks 
are produced at a higher current and lower voltage. So now we have 
three variables that all can change independant of the power input,
we will have to nail down these variables before power has any 
signifiant meaning in relation to spark length aside from the general 
maxium of more power equals longer sparks.
