Thanks!!! I found my problem.
iconian: By far THE MOST IMPORTANT point of
this guide, is to keep notes. If you do not keep notes about what you
hit from what spot, how hard, and how far it was aimed as well as the
result of the shot executed, then you will simply forget the shot you
executed and will be frazzled the next time you get there.
No notes. 18 months wasted :-(
