Okay - on your page now. You have a valid point. My apologies.
I thought your original caution about early missed was directed at his "no warm fuzzy" missed. Then when you said "much further out" from the MAP I definitely wasn't on your page.
One would hope that the other clues that might be available (marker beacon, DME, etc) might get some SA back and avoid the early turn. I'm no terps expert, but it seems like the roughly half mile represented by his 200' early missed on a ~3 degree g/s would still be in the "slop" built into the protected airspace (though certainly not guaranteed, as you pointed out).
