During a buildup check, pressure takes 3 minutes 30 seconds to rise from 50 psi to 90 psi. What is the correct response?

1. Treat it as a failed buildup check because the manual requires 50 to 90 psi within 3 minutes
2. Accept it because any buildup under 5 minutes is fine
3. Accept it if the low-air warning is loud
4. Ignore it because governor unloading is the only pressure test
