Field sobriety tests are 100% bullshit. They are purposefully designed so that the officer can administer the test, you can do everything he says perfectly, and then the officer can write a police report making it look like you failed without technically contradicting the facts. For example they'll tell you to walk the white line. You'll do it easily. Then they'll tell you to do something else. Then they'll write in the report you failed to remain on the white line for the second task even though it was obvious from the context that wasn't the intention of the officer. The prosecutor will ask the cop on the stand "did you ever tell the defendant to get off the white line" and they'll be able to truthfully say no.
