There is (was?) also a book - something like 'Hot Off the Press' by Lori Greenberg. That might help too. It's important to note that not all of the presses start with the same shaped bead. Initiailly that was what took the longest time to 'click' for me - one I figured out that I had to figure out the shape needed pre-pressing for EACH press...then logic took over.
I still have off days...for sure...but it certainly helps have less of them
