I like the fact that we don't have a 180 rule in IDPA.  This allows for more movement and variety in stage design.

That said, unless otherwise specified, we use the 180 as a default at my home range. I have been to some majors, and even SOed at some, where I was amazed at the sloppiness of the muzzle safe points.

I don't think that this is a product of poor rules. It is a product of poor enforcement of safety. Sometimes more than 180 is safe. Sometimes all you have is 90 or less. Use a little UNCOMMON sense and there would be no issue.
