Identify the incorrect statement regarding GFR:
1. The GFR averages approximately 180 L per day (about 125 ml/min).
2. The GFR increases during sympathetic stimulation due to the vasodilation of afferent arterioles.
3. A decrease in GFR results in a decrease in the total urine output.
4. Renal auto-regulation maintains the GFR at a relatively constant rate normally.
