Yesterday while playing a round a couple of people in my group were taking a good deal of photos. After looking at the photos I noticed, when throwing off the tee, that I bringing my left arm up and putting the disc under my arm. Is this really bad form? Am I losing major distance from this? I throw RHBH and I have been stuck at the 275'-300' plateau now for a couple of years. I'm just wondering if this may be a big part of this.
