I've only seen that at the Greek parish nearby, not the ROCOR or OCA parish (I see bowing). Some people cross themselves so fast, it looks like they're just doing three circles in front of their chest. Another thing I noticed at the Greek parish is people will turn to face the priest and censer as he goes about the church. In my parish (OCA), my priest said it's important not to turn your back on the altar; the censing is going to happen whether you look at it or not.
I'm not sure what is more "correct", but you're right, there are more important housekeeping issues
