If you have a very high-powered power supply (i.e. pole pig), you may need a
faster than 120BPS break rate to utilize that power supply.  Consider using
a 15kV 30mA NST vs. a 14.4kV pig.  With a sync RSG, both will charge a 10nF
cap to at least 20kV, 120 times per second, and as such, will deliver
identical power levels.  In order to utilize the far greater power-potential
of the pig, you have to either increase the capacitance or the break rate.
Changing the break rate is much cheaper!

But if you are talking strictly about ~100-120BPS, then agreed, sync makes
much better sense.

But what is the actual difference between ARSG and SRSG? Surely SRSG is best
for everything, becuase it fires as the cap voltage peaks, so you get the
most out of your caps. If you were to use ARSG then you would be using a non
syncronised break rate... why would you want to use that? Even using a
200bps on a 50Hz line seems dumb... why not stick to 100BPS (or 120bps)???
