If an archer has aproblem getting into the target as adressed on some of the posts, and everything seems to click otherwise, the bows tiller may need to be adjusted in either direction to bring more pressure to the top or the bottom limb. This will make it easier to hold on the target without fighting it. It will be you however that makes the decision whether it is a mental or mechanical issue. Usually my tillers are set up exact, however I have had one or two, that shot better with the tiller a little bit out. Most likely it is a mental issue, but once in a while it can be within the bow.....
