I put a clicker on my recurve last fall, started having issues with TP and the clicker helped me get into the hold at anchor and expand pulling through the shot. I killed two whitetails with the clicker, both heard it BTW but died anyhow. I have since removed the clicker, it was a crutch and it did it's job and got me back on track. As far as why I needed it and what really helped me understand was watching a video Tom Clum did where he answered a question that had been in my mind for a long time. The question being; once your bow arm is set do you continue to consciously focus on the spot or focus on increasing tension. Since your conscious mind can only do one thing at a time; The answer was to concentrate on adding tension, Tom gave an excellent example of allowing the subconscious to take over and keep you set on the target. Allowing you to focus on only increasing tension until the shot breaks... it is not as easy as it sounds because for me it felt like I was giving up "control" over where the arrow was going. It took a lot of convincing myself that the "control" came from giving the job to my subconscious and trusting it to do it's job and that only concentrating on expansion gave me better results in tighter groups.
