I'm similar also - I find that people who frown are assuming I must not be able to distinguish between distress and grizzling. If it escalates I'd head in (or kick DH, lol). To be honest, it was less a parenting choice I made and more something that happened because I'd spend 5 of those minutes trying to wake up and Sleep-Nelle desperately begging the baby to stop crying, and by the time I woke I'd usually realise that bub was starting to settle.
