My question on this is where do you draw the line in calling out of your area. I'm sure we've all worked with different officials that we may have felt were subpar at times (I'm sure I've been that official at times myself).
I tend to believe that those that are rating you will clearly see where the weaknesses are in situations like this. At what point does the assignor start seeing you as taking over the game and calling out of your area?
There have been numerous times before on this board where posters have gotten flamed for ball watching and calling out of their area. "Who's paying attention to the other players while you were looking there?"
I think you need to go out every game and do your very best. Obviously, there are times where you might easily be in position to see something in your partner's area, but I would be careful to not overstep your bounds. That could backfire with your partners and assignor.
In addition, there's always the possibility your not as sharp as you think.
