Hi Scott,

In order to target the same charge value at the cap when doubling the 
bps, you can certainly reduce the cap size to 1/2. The energy at the cap 
will reduce by 1/2, but the power across the gap as a function of the 
bps will remain the same.

So if by optimum you mean the same voltage at the cap and the same power 
across the gap, then yes by the numbers. But there are also losses to 
consider as the rate of breaks across the gap has now doubled. Losses 
there are dependent on the gaps efficiency. Some gaps may handle the 
higher bps well with only slight increased losses, where others may be 

Take care,
