Yeah, I think I came up with at least four times that Hawkeye was not looking at what he was shooting at (or, perhaps more accurately, he wasn't looking in the direction that his arrow was currently pointing... when he fires at the engine on the helicarrier, he turns his gaze towards the engine even though his arrow is pointed slightly off to account for the wind). The helicarrier (that I just mentioned), once on the ground (I think) with Widow during the Budapest line, and then at least twice on the roof.
