Yeah it does look like those ones should be quads, I'll see if I can figure out what is happening there.

This one has an easy workaround - it looks like it is only happening at a few particular very rough angles. If you adjust your angle slightly to 57, you should get the same mesh structure but without that one extra refinement:



When you have an angle value that happens to be right near a "boundary zone", it can pretty easily lead to this kind of irregularity. If you want to reduce refinements just a small adjustment in your angle can eliminate it. The mesher is not really very focused on doing such coarse things, I mean it will work but you can run into some slightly odd things at such extreme angles.
