I've used a low frequency for my sessions until now - 3Hz.  In each session I've experimented a bit - number of shocks, number of locations, and shocks per location while keeping the frequency constant.  Now that I've found a combination of these that seems to work best for me (topic for another post, another day - quick spoiler - 11 locations, 300 shocks per location) it's time for me to experiment with frequency setting.

I increased frequency from 3Hz to 4Hz.  My subjective reaction is that it felt like I was being hit a bit harder.  No pain, but definitely more intense.  I think it is an improvement.

Then I boosted frequency to 6Hz.  And quickly stopped the machine.  At lower frequency the regular ping of the shocks is like a metronome - always on the beat.  At 6Hz, I could hear the hand piece skipping and missing shocks here and there.  It appears the software running the machine is just fine, but the hardware has trouble keeping up at that pace.  I suspect that continued use at a high frequency could lead to overheating and perhaps damaging the hand piece.

In the session I did not try 5Hz.  Maybe next time.  But my feeling is that despite manufacturer specifications, my machine's limit is below 6Hz. 

It's sort of a "don't care" for me, as I've been getting good results with a lower frequency.  It's also sort of amusing, as I wondered when and if cutting corners in manufacturing - a Chinese manufacturing specialty these days - would show up.  Finally, it did.
