I find it a bit worrying reading here and there throughout this thread about 'personal adjustments', 15 seconds here, 45 seconds 'special entry' there, and so on. I've spent (too many) thousands of hours in the instructor's chair in the simulator watching students re-draw the Jeppesen diagrams on the monitor over my head. Many of these 'personal adjustments' take them right outside the protected area.
On 99.9% of occasions you'll live to tell the tale, but there are some stinkers out there with very solid obstacles sitting right on the edge of the PANS-OPS protected area.
