Hey all,

I've decided to give making a synchronous gap a go, as I want to 
directly compare the performance with an ARSG. I'm wondering what BPS 
set up is the best to use. The way I see it, to take full avantage of a 
synchronous gap, a 100 BPS gap is the go (for the aussie 50Hz power 
supply) to allow charging at only the highs and lows of the AC 
sinewave. If you increase the break rate above, say, 200 to 400 BPS, 
you are essentially losing the advantage that synchronous operation 
gives, and I would think you might as well use an asynchronous gap at 
these speeds (though an asynchronous gap won't work so well below 
300BPS). However, with the higher BPS you can get by with smaller 
capacitance in the primary circuit. Alot of people seem to compromise 
by using a 200BPS (or 240BPS for you in the US) gap. I'm wondering how 
the 200BPS and 100BPS versions compare in practice.
