* **DEG_TIME** Negative points for extremely fast completion. This value is normed in such way that values of more than 100 points indicate low-quality data. Data quality, however, is no dichotomous attribute. If you prefer a more strict filtering, a threshold of 75 or even 50 points may as well be useful as a threshold of 200 for more liberal filtering.
