This is absolutely correct. The "quarter test" is quick and easy but even after passing it, you can have a severe fogging problem.

Have you checked your enlarger for light leaks? Put a mirror on your enlarging easel, put a lens cap on your enlarging lens, turn off all the lights and then turn your enlarging lamp on. Inspect you enlarger from every possible angle - including from the easel area. You may be leaking white light.
