Eight SEEG sessions averaged 80.4 percent later joint waveform agreement after early shape selection with a size factor of 1.25

## Result An early waveform shape check selected 196 of 886 eligible SEEG readouts in eight patient sessions. The mean rate of later shape agreement was 94.5 percent. The mean rate of joint shape and voltage size agreement was 80.4 percent. The difference was 14.1 percentage points. Each patient had equal weight. The descriptive 95 percent patient bootstrap interval for the difference was 8.9 to 21.8 percentage points. A shape match required a correlation of at least 0.8. A joint match also required a later-to-early voltage size ratio from 0.8 to 1.25. This interval uses a factor of 1.25 in either direction on a log scale. It permits a 20 percent decrease or a 25 percent increase. It is an example engineering tolerance. It is not a clinical standard.
