I have had MANY field sobriety tests in my life. Where I used to live was a bar-crawl district and cops had a tendency to profile people based on what they are driving and where they are. Sadly, I lived a block away from the main strip, so I was pulled over and tested a LOT. The good news is, since I lived so close, I could park at home and walk to the strip, heh.

I was given one test years ago however where I did have couple of drinks. The sobriety was not an issue and the breathalyzer was well within the state limit, but I was still ripped a new one since the cop was the in charge of the "anti-street racing and drinking/driving unit". He was a good old boy with a chip on his shoulder and no matter how respectful and well mannered I was with him, I was still the scum of the earth. I was written up for quite a few things, but not what he really hoped to write me up for.

In the end, no matter how much you have to drink, the officer still has the right to subjective opinion on whether you are suited to drive or not (so it is here anyways). They will not/ can not arrest you for the offense, can ask that you call someone to pick you up at the pull over location to drive you home.
