That's one way of doing it. David OJ says they did it by visual inspection of 
the EEG, which 
is generally more accurate. The MOST accurate way of doing it is to have one 
(or more?) 
time-coded video camera on the person and deleting any EEG that occurs when 
there is a 
visible twitch, but I don't think most researchers  bother with that, at least 
not these days.
