For our surface stim paradigm, the longest pulse we use is 500 usec (with a 2500 usec recovery phase). So if we assume a 3000 usec (3 ms) total pulse time, at 100 Hz we could conceivably do 3 channels with this setup, correct? Or, if we go down to 2 ms total pulse duration, including recovery, we could easily do 4 channels at 100 Hz. At lower frequency, we could then go to more channels, i.e., at 50 Hz, we could do 8 channels with 2 ms total pulse duration. Is my thinking correct here?
