Broadly, yes.Q. And that a TASER M26 is designed to, I'll sayfire -- maybe you don't like that word -- 15 to 20pulses a second.A. Correct.Q. Is that correct?A. (No verbal response.)Q. How was that number, how was that pulsefrequency arrived at?A. Theoretically and experimentally.Q. Can you sort of summarize how it was arrived attheoretically?A. Certainly. Theoretically, individualelectrical pulse discharges will stimulate excitabletissues, particularly the motor nerves of the targetsfor the M26. So a singular pulse will cause a twitch.As pulses are then repeated, those individualtwitches -- for example, at two pulses per second, onewould see a twitch, for example, like my hand, a twitchand relaxing. But a subject can continue to movethrough twitches. At about ten pulses per second, aphenomenon called clonus begins to occur. That's where
