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.
