Mine, when I got it was in the middle position. It goes from the middle point, two down or two up, then all the way down. Why they do that, I don't know. At any rate, it's obvious that once it's in position 6 it's there to stay unless you take the shock off or maybe put the bike on a jack.
Anyway I set mine to all they way soft, and it felt pretty good. But I am a man, and a man who sets performance above comfort

So, I raised it to 5 (hard) and decided it was a little bit more bumpity than I wanted, and not that I couldn't take it, of course being a man who cherishes performance over comfort, but I wanted to see if setting 4 would provide better performance at the risk of also providing more comfort.

So, when I went to make the adjustment, I could not remember which way to turn it. Since I am a man and don't like to rely on printed instructions (it would uncomfortably close to referring to a map, after all) and I did not feel like walking inside the house to get the book, so, since I am also a man of logic, I deduced that I had a 50/50 chance of getting it right.
I never have been a very lucky person, so after turning the wrong way, I went ahead and did the other shock to match and have been riding along very comfortably ever since.
