Listen to your gut feeling. Retirement falls in the "better to have it and not need it" category. "When you need and don't have it (money)" will spell troubles in the old age. Just because someone else didn't see SORR doesn't mean you won't see it. I always say that for a retirement longer than 30 years, one should use lower than 4% WR. FWIW we use 3% WR for a 40 years retirement. YMMV.
