Since the collar hasn't been shortened it takes fewer turns to bottom out then more turns. What part of that don't you understand?
Read the instructions again. It says remove the collar and lock washer, then count the turns. This will be the most turns you can get. If the collar is taller you would end up with fewer turns.
In my case I bottomed at 6 3/4 turns and with the collar only 6 turns so I had to shorten the collar. In fact, with closer inspection, who ever worked on the collar didn't true it up. By truing it up I got the right number of turns.
